over.
It is the same (1 left over) when he groups them with
3, 4, 5, or 6.
When grouped with 7, there are none left over.

Show your strategy for full credit!

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

The answer here would be 10
