Tessa designs a supply closet as an addition to her house. The closets sides are 3ft,
8ft, 2ft, and a question mark. It is a total area of 36 square feet. What is the length in feet of the side of the supply closet labeled with a question mark?
To calculate the missing side length of the supply closet, we first need to find the perimeter of the closet using the given sides.
Perimeter = 3ft + 8ft + 2ft + x (question mark side)
Perimeter = 13ft + x
Since the perimeter of a rectangle is the sum of all its sides, we can set up the equation:
13ft + x = 2(3ft + 8ft)
13ft + x = 2(11ft)
13ft + x = 22ft
x = 22ft - 13ft
x = 9ft
Therefore, the missing side length of the supply closet labeled with a question mark is 9ft.
