Step-by-step explanation: The swimming pool is not a square. This is because if you find the square root of the given area, it will not give you the given length. So the swimming pool has length and width of different dimensions. It is a rectangle. The formula for the area of a rectangle is expressed as Length × width.
The length of the swimming is given as 20 1/4 yards = 20.25
The area of the swimming is given as 256 1/2 square yards = 256.5 square yards
