The area of his bedroom is 90, and the area of his bedroom is 9 times the area of his closet, so divide by 9 to find the area of the closet.

90 / 9 = 10

So the area of the closet is 10 square feet.

I’m guessing the closet is a rectangle shape.

The formula for the area of a rectangle is A = lw.

Plug in what we know:

10 = l(2)

Divide 2 to both sides:

l = 5

So the length is 5.
