To find the measurement of a piece of land, or how many acres it is, one should find the area of the piece of land first. To do this, multiply the length by the width (in feet). This will give you the square footage or area of the piece of land. There are 43,560 square feet in an acre of land. Once you have the area of the piece of land, divide it by 43,560, this will give you the number of
. acres or what fraction of an acre the square footage is. For example, if your piece of land is 87,120 square feet, you would find the acreage by dividing 87,120 by 43,560. 87,120/43,560 = 2 Acres. So you have 2 acres of land. Now if your land is less than 43,560 you would find the fraction of an acre that your land represents. For example, the square footage of your land is 21,780. To find the acreage you would divide 21,780 by 43,560. 21,780/43,560 = .50 acres which is the same as 1/2 acre. So you have a half acre.
