021The new facility is square in shape. The length of one of the walls (see below) is 20 feet. How many square feet is the facility?

Answer 1

The area of a square is calculated by squaring the length of one of its sides. In this case, the length of one of the walls is 20 feet.

Area = 20 ft x 20 ft = 400 square feet

Therefore, the facility is 400 square feet in size.
