I colour coded them so it would be easy to point out what goes where Ex:
Poly: blue green, etc.
Non poly: pink purple, etc.

I think your answers are
Poly:red purple blue
Non poly: yellow green white

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
