Hello! I have a few questions regarding my geometry homework. I have them answered already, but I want to double check. 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:

Adult pinball machine GAME with base ME measuring 35 inches and sides measuring 56 inches. Child pinball machine G prime A prime

If the perimeter of the adult pinball machine is 167 inches, what is the length, in inches of Segment line G prime A prime ? Type the numeric answer only in the box below.

Pentagon OPQRS is shown on the coordinate plane below:

Pentagon OPQRS on a coordinate plane with ordered pairs at O negative 1, 2, at P negative 5, 3, at Q negative 3, negative 2, an
If pentagon OPQRS is dilated by a scale factor of seven over four from the origin, to create O'P'Q'R'S', what is the ordered pair of point S'?

A. (1.75, 3.5)
B. (3.5, 8.75)
C. (1.25, 0.75)
D. (8.75, 5.25)

I got D. (8.75, 5.25) with the help of my mom but I'm still a bit unsure.

Hexagon IJKLMN is shown on the coordinate plane below:

Hexagon IJKLMN on a coordinate plane with ordered pairs at I negative two, six, at J four, four, at K six, negative one at, L n

If hexagon IJKLMN is dilated by a scale factor of two fifths from the origin to create hexagon I'J'K'L'M'N', what is the ordered pair of point I'?

A. (−5, 15)
B. (−0.8, 2.4)
C. (−2.5, 5)
D. (−0.4, 0.8)

And that's all, thank you so much if you help. Geometry is a bit hard for me.
