Tessa designs a supply closet as an addition to her house. The closet is pictured, and its total area is 36 ft.². What is the length in feet of the side of the supply closet labeled with a question mark?

1 answer

Based on the picture, the supply closet is a square. Since the total area of the closet is 36 ft.², we can find the length of each side by taking the square root of the total area:

Side length = √36 ft.²
Side length = 6 ft

Therefore, the length of the side labeled with a question mark is 6 feet.
