If an acre of land is square what would be the outside dimension?

One acre is 4,840 square yards or 43,560 square feet, and so a square piece of land measuring 208.71032 feet on all four sides is approximately an acre. The number of sets of dimensions that will equal an acre is infinite. For instance, a piece of land 10 feet wide and 4,356 feet long is exactly one acre because 10 x 4,356 = 43,560. Moreover, a piece of land 30 feet wide and 1,452 feet long is an acre because the two dimensions equal 43,560 square feet when multiplied.

Even circles can be acres! In fact, a circle having a diameter of 235.564 feet is approximately an acre because the formula for determining the area of circles proves that such a circle is almost equal to 43,560 square feet.
