You need to know one of the dimensions.

Unless the land is a perfect square, you need to know at least one dimension in addition to the area. Either the length or width, and you can calculate the other.

An acre of land is 208' by 208'


A 10 acre piece 2 acres deep (416') would have a length of 5 acres (1040')

dividing it in half along its length would leave you two peices of land roughly 416' by 520'

How Do You Figure Acreage?

Do you want ot end up with two triangles, or one triangle, and one triangle shape with the top chopped off? I can't remember what this shape is called, sorry. You might be best to draw the original, complete shape to scale on a peice of paper, with the correct dimensions and angles for each side, and then draw a line where you want the disecting line to be. You should then be able to measure the lengths off on your peice of paper. Good luck with this.

i have some land 495' ft by 495', how many acres is this?

Robert Fogt
03-15-2006, 01:51 PM
495 feet * 495 feet = 245025 square feet

245025 square foot / 43560 = 5.625 acre

what is acreage for 162' x 269' ????

Robert Fogt
03-19-2006, 06:42 PM
162 feet * 269 feet = 43578 square feet

Since 1 acre = 43,560 square feet, I would estimate the above and call it 1 acre, though technically its 1.0004 acre.

Robert Fogt
03-23-2006, 01:36 PM
43,560 square feet / 386 feet = 112.85 feet

Though an area of land 586 feet by 386 feet is 5.19 acres, not 2.12 acres.

neat forum, maybe you guys can help me with something.
I figure since this string is about acres, i'll post my question here.
I do clearing with heavy equipment and on this certain job its paying "per acre" instead of by the job, or equipment hour, which is the norm for me.
anyway here is my question.
I know that an acre is 208.7 feet X 208.7 feet

I have 2 roadways to clear. One is 30' wide, and the other is 85' wide.

could I figure the acres as follows?

208.7' - 30' = 178.7' , then add the 178.7 from side "A" to the
208.7' on side "B" to equal 387.4' , simply making a "square" into a rectangle.
adding the subtracted footage off one side to the other side to figure the acreage of the cleared roadway?

Robert Fogt
03-26-2006, 09:53 AM
Just multiply the width in feet by the length in feet to get the square feet. Then divide by 43560 to get acres.

So if you're clearing a road 30 feet wide that is 500 feet long:
30 feet * 500 feet = 15000 square feet
15000 square feet / 43560 = 0.3 acres

Robert Fogt
04-01-2006, 09:33 AM
That's called an irregular polygon, and you cant calculate the area without additional information.

The easiest information to gather would be the length of at least one of the diagonals. Though if you could also measure the angles that would work too.

The way these odd shapes are calcuated is by splitting them up into two triangles and measuring the area of each. That is why you need to know the length of the diagonals.

Robert Fogt

Those are irregular shapes and you would need more information to calculate the area. For example, you could measure the diagnals. You split the irregular polygon into multiple known shapes (triangles) which you are able to calculate the area of.

Though if the land is fairly rectangular in shape, I see nothing wrong with estimating. For example, turn a 280' x 115' x 275' x 120' irregular polygon into a 280' x 115' rectangle which requires nothing more to calcuate the area of.

That's what we call an irregular polygon, and you need more information before being able to calculate the area. If you could measure the diagonals we could calculate.

Basically we have to break up the irregular shape into known shapes we can calculate, such as two triangles.

Robert Fogt

I can calculate it, but you will have to draw it.

To calculate an irregular polygon, you have to break it up into known shapes and calculate each seperately.

If you can draw it out in a paint program, label all the side lengths, it would work. Or draw it on paper and scan it in.

If you can measure an angle, thats all I would need. If you can draw the shape and send it to me I could measure an angle.

To calculate the area of an irregular shape, you need to split the shape into smaller shape which you can calculate.

For example, to calculate something thats like an ice cream cone shape, you would split it into a triangle and a half circle, calculate the area of each then add together.

So you'll need to split up your pond into shapes like squares, circles, triangles, etc and measure each shape.

just divide it in half

That will only work if the area is a rectangle or trapezoid shape. If the sides go off at angles, such as a parallelogram, it could be way off.

I would not recommend using that method unless the shape is close to rectangle.

Hi,

If it is almost a rectangle, then you can just take an average of the ends and the sides to get an approximation.

i.e. you rectangle is about 315 x 130is approximately 40000units². If your original units are meters, then this is about 10 acres.

how many feet (not square feet) in one acre?

An acre is a unit of measurement of area.
So it is 43560 square feet.
Are you asking about one of the dimensions of a square acre?
If the acre were a perfect square you would use the square root of 43560 and that would be approx. 208.71 for one of the sides.

Sandra
11-09-2007, 08:08 AM
440 by 310 how many acres is this

assuming that you are giving your measurements in feet.

440 x 310 = 136400 square feet

since there a 43560 square feet in an acre

136400 / 43560 = 3.13 acre

[I need to know how many feet there are to fence in 5 acres.

there are 43560 sq. ft. per acre x 5 acres = 217800

to get one of the dimensions you need the sq. root of 217800

466.7 ft.

466.7 x 4 for the four outer dimensions to get total feet of fence

1866.8 feet of fence

This is basically an estimate and would work well for a square or rectange because the dimensions would work out to about the same in total.
If the shape is unusual you would need to allow extra fencing.

i m looking to buy some land i have 2877.95 ltft as my perimeter what is my acreage and how did you figure it

The perimeter doesn't help much unless you know the shape.

If it is square (all sides equal, all corners 90°), each side is 719.4875 ft, and the area 517662 ft² or 11.88 acres.

However, it could be an absurd shape, like a rectangle 1437.975 ft long, 1 ft wide, and area 1437.98 ft².

You really need to know all the sides (in order) and their bearing angles, or the angles in all the corners.

A circle has the highest ratio of area to perimeter, so by assuming a circle, you can set an upper bound to the area from the perimeter, but it can be ANY smaller number, down to and including zero, so the perimeter just doesn't tell you much useful. I guarentee it is LESS THAN 659108 ft²

It's as simple as base times height only divide the sum by 2. take 1930 x 1676 it should come to just over 3.2 mil sq ft. divide that by 2 and get approx 1.6 mil sq ft. now take what ever an acre sq ft. is 43,000-45,000 and do the math. the answer is approx 37acres

1 acre is 43560 ft², so 0.53 acre is 23087 ft². If one dimension is 98.46 ft, and rectangular shape, the other dimension is 234.5 ft.

If acreage has been rounded to 2 digits, the answer is too, so 230 ft approx.

567 300 ft² x 1 acre/43560 ft² = 13.02 acre.

You can work the 2nd one the same way

It's a triangle? You can work out the area by Heron's formula, and it is 34188 ft². An acre is 43560 ft², so 0.785 acre.

an acre of land is 43,560 sq ft how long is one side of a square acre

sqrt(43560 ft²) = 208.71 ft approx

This is rounded. If you square it, it falls about 0.07 ft² short, but 208.72' on a side is more than 4 ft² over an acre.

You can calculate the area of a triangle from the three sides using Heron's formula. We have a calculator that implements it:

What a great thread! My math is pretty bad and I am trying to figure out what the mileage would be for running around a 100 acre property line. The land is a combination of sand, mud, shallow marsh water and grass. It is pretty much a rectangle shape.

Does anyone know how many miles that would be? Or the easiest method to calculate it?

Thanks!

If it were square, it would be about 8350 ft (1.6 mile). If it is rectangular, and the same area, the perimeter will be greater. The amount will depend on aspect ratio (how long and skinny of a rectangle it is)

In a Nut Shell.... Did you have a survey? If you did, request a copy....it's yours, you paid for it!!! If not, go to your county office (where you pay taxes) and they can print an aerial image of the properties under your name or in the name in which you took title (The name on the deed). If the printed image doesn't display the dimensions ask for them to switch to a different screen. Most, but not all counties can do this. Keep in mind, should you have 50 acres and they're only charging you for 40 acres your taxes on the property, the tax will increase should you bring this to attention. Ask what's in your name or what you have... ask for them to print and pay a few bucks. (Approx $1.00 per page)
An acre has 43,560ft. and it can be in any shape. Without accurate dimensions, it can be tricky to calculate.
*Most people asking these questions want details to construct on or close a property line. If a building should encroach on the adjoining owner, that owner has every right to have the given portion of a structure removed...what ever touches the neighbor's property. Who wants to have 2ft of their new shop sliced and diced? Without a survey this could be expensive and create problems should you or your neighbor want to sell. Depending on the sale this could be an issue, it would give a buyer a way out of the purchase and a lender would want this corrected if the person it getting a loan. A fence on the other hand is easy to remove, but still a hassle.
Know what's yours and when buying a property, calculate and match the legals with what is being purchased. (Even though your legal may state ???ft x ???ft and so on, you can ONLY assume where the point of beginning is. Check it and check it twice. A deed is a document that is conveyed, from seller to buyer. The legal is all the mumbo jumbo IN THE DEED. Example of a legal- Ne1/4 SW1/4 and S1/2 SW1/2 of Section 16, Township 11 and Range 14E .....of ? County.
Hope this helps.

Robt: I have a 3 acre yard with a very irregular shape and a house in the middle of it. I wish to map out a half acre piece at a time for purposes of clearing and planting new grass. Since a half acre is approximately 21780 square feet, which on a rectangle translates to 165 x 132, would it work for me to get a piece of string which measures 297 feet, lay out the shape I want, and know that within the perimeter I have captured a half acre? Thanks in advance for your help with this.

The perimeter of a 165 x 132 ft rectangle is 594 ft (two of each side), and you have to get the sides right and 90° angles to have a half acre. With four equal sides, the same perimeter gives a little more area, 22 052 ft², in a circular shape, the same perimeter gives over 28000 ft², and in a long skinny rectangle, less than a half acre.

10 acres is 435600 square feet, 5 acres is half that. But how to divide into two parcels depends on the shape of the lot, road access to both parcel after the split, and some definition of about where you would prefer the split to be. Then area calculations can determine the exact location mathematically.

I'm not sure what you are asking. If you want a house plan, we're not architects and can't draw you one. Your lot if rectangular is 1500 ft² or 0.034 acre.

For the area of a four-sided figure, we also need the corner angles.

Your dimensions appear to have a problem as millimetered squared is a unit of area not of length.

Indeed, something seems lost in the translation.

But here is a quick visual for 1 acre.

" American football is played on a field 360 by 160 feet (120.0 by 53.3 yards; 109.7 by 48.8 meters)." from Wikipedia


53.3 Yard x 90 Yards = 0.99116 Acre

So from one Goal line ( 0 Yard line) to the 10 Yard line at the other end ( ie 90 Yards from the reference Goal line) is very very close to one acre.

Be aware that the 'end zones' are 10 Yard each as well! So if you visualize from the back of the 'end zone' instead of the zero yard line, adjust accordingly.

(Many people, including me, believe the field is 50 yards wide, I do not know, but use wikipedia's 53.3 yards; it does make since if it was all originally defined in feet:) )

The Property I Am Looking At Is Not Square But More Of A Triangle Area. The Footage On Each Side Is As Follows:

Side A= 1930 Feet
Side B= 1676 Feet
Side C= 2316 Feet

How Do You Figure Acreage?

You use what is called the Cosine Rule. You only need two adjecent sides (e.g. A, B)but you also need an included angle (e.g the angle between A and B).
Side A= 1930
Side B=1676
Included Angle= ????? Say 30°
Area = 1/2*A*B*Cos included angle
in this case it equals 1400657 square feet

Actually, that is 1/2*A*B*sin(included angle). You can solve for the included angle using the law of cosines.

Alternatively, you can use Heron's formula
s = (a+b+c)/2
A = sqrt(s*(s-a)*(s-b)*(s-c)) = 1 590 670 ft²

An acre is 43560 ft². Under PLSS system, a section is 640 acres or 1 sq mile, a quarter quarter section is 40 acres and is square, 1320 ft on a side. I assume you have two adjacent plots so 1320 ft by 2640 ft.

5 acre is 217 800 ft², but could be any length and width whose product is this number. A slice the full 1320' depth of one side is 165 ft
But it could equally well be 330' x 660' or 440' x 495' or numerous other dimensions. Pick one side and divide into 217 800 to get the other side.

The acre is a unit of area (43560 ft²/acre), not a unit of length.

If your shape is rectangular, multiply length and width, both in feet for square feet. Divide by 43560 for acres.

If the shape is other than a rectangle, the formula for area will be different.

You need to know one of the dimensions.

Unless the land is a perfect square, you need to know at least one dimension in addition to the area. Either the length or width, and you can calculate the other.

10 acre x 43560 ft²/acre x 1/200 ft = 2178 ft

This assumes the shape is a rectangle, and the area is exact.

Just come across this brilliant website -- sketchandcalc -- . -- com. Draw the shape of your piece of land in metres and it will give you square metres then use an online calculator to convert to Acres. It's not exactly 100% as you are drawing the shape but if you know the rough shape of your piece of land it's pretty good.
