The perimeter of an acre-sized plot is equal to the number of linear feet around its perimeter. However, the real perimeter depends on whether the area is square or circular.
An acre has a surface area of 43,560 square feet. Each side of a perfect square acre is approximately 209 feet long. The perimeter is the sum of each side’s length, or roughly 836 linear feet. If the perimeter of an acre is circular, the number of linear feet matches the plot’s circumference, or 740 feet. The perimeters of irregularly shaped acres vary in length dependent on their unique shape.
