Question

60 inches of plastic are folded to make a picture frame.

 

The height of the finished frame is 6 inches. How long is the frame

Answer 1

This is a perimeter problem. If one side is 6 inches, that means the side across from it is also six inches. We need to find the other side length. All sides added together will equal 60 inches.

 

P = 2L + 2W

 

60 = 2(6) + 2W

 

60 = 12 + 2W

-12   -12

 

48 = 2W       W = 24 inches
