What is the perimeter of 22 acres?

It depends on the shape. 22 acres =106480 sq yards. If it is a perfect square, with all sides equal and all angles right angled, the length of the sides will be equal to the square root of 106480 = 326.31 yards, so the perimeter will be four times this = 1305.25 yards. If it is a long rectangle, the perimeter will be bigger. A circle gives the smallest perimeter possible.
