Question

Pls help, urgently!!!

Answer 1

No, because the friend counted a length that is inside of the polygon, which you don't need for finding the perimeter, since the perimeter is the sum of the outside lengths of the polygon.

Answer 2

Yes, no is correct

Explanation:

This is because you only add up the outside sides of the polygon to find the perimeter. None of the inside sides. Hope this makes sense and hope it helps.
