Tessa designs a supply closet as an addition to her house. The closet is pictured, and its total : is 36 square feet. What is the length in feet of the side of the supply closet labeled with the question mark? (1 point)
The supply closet is in the shape of a square. Since the total area is 36 square feet, we can find the length of one side by taking the square root of 36.
√36 = 6
Therefore, the side labeled with the question mark is 6 feet long.
