Answer 1

So can you define perimeter first off?

Answer 2

no

Answer 3

Cool cool - the perimeter is the total length of the sides of a given shape. So for the first shape, a triangle, there are three sides, so you can find the perimeter by adding up the lengths of all three sides. What might that be?

Answer 4

17

Answer 5

Yup yup ^_^

Now, for the next one, you add up the lengths for all of the outer sides again. What does that give you?

Answer 6

22 and 27

Answer 7
