Answer 13

Well, this is very sloppy, but I did this on graph paper. I counted 15 squares of 2 cm each on opposite sides

and I counted 22 squares of 2 cm each on opposite sides.

So That's a total of
15*2 = 30
22*2 = 44

Which is at total of 74, however, since the corners run into each other and the corner pieces are included in both sides and there are four corners, you have to subtract 4 because of "overcount", so actually, there are only74 - 4 or 70 pieces along the edges.
