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?

1 answer

Since the facility is square in shape, all four walls will have the same length of 20 feet. To find the total area of the facility, we need to calculate the area of a square with one side length of 20 feet.

The formula to find the area of a square is:

Area = side length x side length

Plugging in the side length of 20 feet:

Area = 20 feet x 20 feet = 400 square feet

Therefore, the facility is 400 square feet in size.
