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?

feet

Answer 1

Split the shape into a top rectangle (width ? and height 3) and a left bottom rectangle (width 2 and height 5, since 8 − 3 = 5).
Area = 3(?) + 2·5 = 3? + 10 = 36.
So 3? = 26 and ? = 26/3 = 8 2/3 feet.
