    convert feet to acres

    I have a parcel of ground that is 450 feet long and 250 feet deep, how do I convert to acres?...

    Re: convert feet to acres

    Assuming it is a perfect rectangle

    450 x 250 = 112,500 sq ft

    112,500 / 43,560 (Acre) = 2.58 Acres

        Lots with 4 or more sides can have multiple shapes depending on the corner angles. Without the corner angles (or the bearing angles of the 5 sides) there is no way to answer this question.

          If there are no right angles then the easiest thing is to make 5 triangles, divide each into a right triangle, compute each right triangle (base x height = square feet) then add the 5 together. So you won't be confused, to get the area of a right triangle it is base x height / 2; however you are actually creating 2 identical triangles by making the right triangles because the b side (height) bisects the length of each of your 5 sides, so the sq ft of each of the 5 triangles is two times the sq ft of each right triangle.

              The shape (and area) is not fixed by four sides alone. We need a diagonal, or the corner angles, or the bearing angles of the four sides.

                four different measurements.

                East Side: 205.1 Feet
                North Side: 190.4 Feet
                West Side: 206.6 Feet
                South Side: 67.4 Feet

                What is the total area in feet and convert this to acres, please.........

                  I have a parcel of land that measures 110 ft wide and 250 feet deep. What does this come out into acreage?

                    Assuming it is rectangular, four 90° corners

                    110' x 250' x 1 acre/43560 ft² = 0.63 acre

                        80 feet * 120 feet = 9600 square feet

                        There are 43560 square feet in an acre, so:

                        9600 square feet / 43560 square feet/acre = 0.22 acre

                        You have (very) slightly less than 1/4th an acre.
