Question

Crystal's bedroom has an area of 54 square feet. The bedroom is 9 times as many square feet as Crystal's closet. If the closet is 3 feet wide, what is the length of the closet?

Step-by-step explanation: First, use comparison to find the area of the closet. Then using the area of a rectangle formula, work backwards to find the length, since we know both the area and width. See the attached image for working.
