If you have a perfect square that is equal to 1 acre, what is the length of the sides and how do you do it? One acre is 43,560 square feet so a square, with area one acre would have a side if length the square root of 43,560 or approximately 208.71 feet.
One acre is about 4,046.873 square meters. A square plot of ground 208.7 feet on a side will cover an acre. An American football field, 360 feet by 160 feet, is about 1.3 acres; 12 high school basketball courts are a little more than 1 acre.Here's a way for city dwellers to use a Google map of their neighborhood to get a feel for how big an acre is.or example, imagine a sidewalk 5 feet wide. If it were (43560 Ã· 5 =) 8712 feet long it would take up an acre, a long skinny acre. On the other hand, if the 1-acre lot were a square, its sides would be only 208.7 feet long.
