Question from Amanda, a parent: What is the perimeter of a square acre? Answer in feet, please. |
Amanda,
An acre is 43560 square feet o it it's a square of side length s feet then s2 = 43560. Hence s = √43560 = 208.71 feet. There are 4 sides to the square so the perimeter is 4 × 208.71 = 834.84 feet.
