Question

If the perimeter of the adult pinball machine is 172 inches, what is the length, in inches of G' A ' ?

Answer 1

The perimeter is the sum of the 4 sides. The 3 sides given sum up to 147 inches.
The perimeter is given as 172 inches. The difference is the length of GA

Answer 2

but they want the length of G'A' (the kid pinball machine) so the answers 10 right

Answer 3

Well then, you are going to have to make some assumptions. One assumption is that the child machine is a scaled down adult machine 14/35. Then solving for the adult GA it is 25 in. so the child would be 25*(14/35)=10 inches for G'A'
