If one acre is a square (two-dimensional figure with four straight sides, whose four interior angles are right angles and whose four sides are of equal length), each side is 208.7103 linear feet (square root of 43,560). The perimeter would be 834.8413 linear feet (208.7103*4).
In the United States, because the acre is a land measure it is currently based on the U.S. survey foot and not on the international foot. One acre is about 4,046.873 square meters. A square plot of ground 208.7 feet on a side will cover an acre.
