I know there are 43,560 square feet in 1 acre of land.

If that acre were completely square what would be the perimeter of the square.

I appreciate your time and attention to this matter. I am trying to construct a 1 acre pen for livestock.



Hi David,

The area of a rectangle is the length times the width. In a square the length and width are equal so you are looking for a number x so that x   x = 43560. In other words x2 = 43560 and hence x is the square root of 43560. I used my calculator to find √43560 = 208.7 and hence if you make your pen 208 or 209 feet square you will have an area of approximately one acre.
