To find the area of the swimming pool, we need to find the area of the original rectangle and then subtract the area of the rectangle that was removed.
Area of the original rectangle:
Length = 8 yards
Width = 7 yards
Area = Length x Width
Area = 8 yards x 7 yards
Area = 56 square yards
Area of the removed rectangle:
Width = 3 yards
Length = 7 yards (original length) - 3 yards (width of removed rectangle) - 3 yards (remaining width)
Length = 1 yard
Area = Length x Width
Area = 1 yard x 3 yards
Area = 3 square yards
Area of swimming pool = Area of original rectangle - Area of removed rectangle
Area of swimming pool = 56 square yards - 3 square yards
Area of swimming pool = 53 square yards
Therefore, the area of the swimming pool is 53 square yards.
