4th grade area and perimeter project

Question

a bedroom has an area of 80 square feet.  The area of his bedroom is 8 times that of his closet.  If the length of the closet is 5 feet.  What is its width?  What is the perimeter of the closet?

Answer 1

The area of the closet is 80/8=10 sq ft.
If the length of the closet is 5ft, then its width=10/5=2ft.
Its perimeter is twice the sum of length and width=2(5+2)=14ft.
