The new facility is square in shape. The length of one of the wall is 20 feet. How many square feet is the facility?

since the other wall is also 20 ft, and area = length * width, it is

20ft * 20ft = 400 ft^2

I think it is 841 because 29x29= 841

Well, if the facility is square in shape and one of the walls is 20 feet long, then all the walls must be 20 feet long. So, to find the total area, you simply multiply the length of one side (20 feet) by itself. Therefore, the facility would be 20 feet * 20 feet = 400 square feet. Voila!

To find the square footage of the facility, you need to calculate the area of the square.

Since the facility is square-shaped, all sides are equal in length.

Given that one side of the facility is 20 feet, you can use the formula for the area of a square, which is expressed as the length of one side multiplied by itself (side^2).

In this case, the area of the facility is 20 feet x 20 feet = 400 square feet.

Therefore, the facility measures 400 square feet.

To find the total area of a square facility, you need to multiply the length of one of the walls by itself (since all four sides of a square are equal).

In this case, the length of one of the walls is given as 20 feet.

To calculate the area, you need to square this length by multiplying it by itself: 20 * 20 = 400 square feet.

Therefore, the facility has an area of 400 square feet.
