Explanation:

Step1: Find closet area

Since the bedroom area (72 square - feet) is 8 times the closet area, we divide the bedroom area by 8.
$72\div8 = 9$

Step2: Find closet length

The area of a rectangle is $A = l\times w$. We know $A = 9$ square - feet and $w = 3$ feet. To find the length $l$, we use the formula $l=\frac{A}{w}$.
$l=\frac{9}{3}=3$

Answer:

The area of the closet is 9 square ft. The length of the closet is 3 feet.
