Tessa designs a supply closet as an addition to her house. The closet is pictured, and its total area is 36 square feet. What is the length in feet of the side of the supply closet labeled with the question mark?
To find the length of the side with the question mark, we need to divide the total area of the supply closet by the known lengths of the other sides.
Area = 3 ft. * 8 ft. = 24 square feet (for the two sides to the right of the question mark)
24 sq. ft. + 2 sq. ft. = 26 sq. ft. (adding the third side)
36 sq. ft. - 26 sq. ft. = 10 sq. ft. (the area of the side with the question mark)
Now, to find the length of the side with the question mark, we divide by the known length of the side to its left:
10 sq. ft. ÷ 2 ft. = 5 ft.
So, the length of the side with the question mark is 5 feet.
