Because an acre is an area measurement, it is not possible to convert it into feet, which is a length measurement. An acre is defined as being equal to 43,560 square feet. With this information, it is possible to find the dimensions of an acre in feet that has either a square or rectangular shape.
Although an acre is equivalent to 43,560 square feet, it can have different shapes, including a triangle, square, rectangle or circle. If the acre is shaped like a square, the formula for the area (A) of a square is equal to side (s) squared or A= s^2, Since the area is equal to 43,560 square feet, then the length of each side (s) is found by taking the square root of 43,560 square feet, which is approximately 208.71 feet. So an square acre is 208.71 feet by 208.71 feet.
For an acre that has a rectangular shape, the area formula is given as length multiplied by the width. Since the area is 43,560 square feet, the multiplication of length by width dimensions of the acre must be equal to this area. This means that a rectangular acre can have any dimensions, such as 1 foot by 43,560 feet, 2 feet by 21780 feet, 10 feet by 4356 feet or 660 ft by 60 feet.
