Please help me solve :) A toy company manufactures arcade games. They are marketing a new pinball machine to children. It is similar in size to the adult version of the same game. Both the adult and child models are shown below: If the perimeter of the adult pinball machine is 177 inches, what is the length, in inches of Segment line G prime A prime? Type the numeric answer only in the box below.

    find GA using the given perimeter find the scale factor (they're similar polygons)

    Is the scale factor 2.5?

    looks good. 30 is correct. next, we just set up a proportion. \(\dfrac{GA}{G'A'}=\dfrac{EM}{E'M'}\\\dfrac{30}{x}=\dfrac{35}{14}\) or you can just use the scale factor and so we know that 2.5*\((G'A)'\)=GA so we can do \(2.5x=30\\x=\dfrac{30}{2.5}\)

    so line G'A' would be 12 inches?
