Can someone help me with this geometry word problem?

Question

Matt has two posters for his science project. Each poster is a rectangle. The length of the larger poster is 11 inches. The length of the smaller poster is 6 inches. What is the perimeter of the smaller poster if the perimeter of the larger poster is 60.5 square inches?

Answer 1

If the lengths are in the ratio of 11 : 6, then the perimeters are in the same ratio,

p : 60.5 :: 11 : 6

Can you solve for p and asnwer?
