If a swimming pool has a perimeter of 132 feet and is 21 feet wide, what is the area?

945 square feet

Explanation

The formula for area = length times the width. The perimeter is the distance around a shape. So for a rectangle that is 21 feet wide (twice), start with the perimeter 132 and subtract 21 feet (twice): 132 – 42 = 90. This means the other 2 sides are each 45 square feet. 45 * 21 = 945 square feet for the area
