Question

jackson's bedroom has an area of 90 square feet. The area of his bedroom is 9 times that of his closet. If the closet is 2 feet wide, what is the the length?

Answer 1

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.
