Answer 1

@hero?

Answer 2

So you see the octagons on the top and the bottom? Their edges will connect with the edges of the squares in between them, so we don't need to worry about counting those.
The only edges you need to count are the ones on the squares... But be careful: you don't want to count the edge on the outside twice!

Do this and tell me what you got.
