Answer 2

Your diagram makes it hard to see that many of its sides are the same length..but

I'd just calculate each side with a a simple length times width.

in this case it would be

(8x5)2
(13x8)2
(13x5)2

Answer 3

SO just calculate all those values and add them up

Answer 4

209

Answer 5

You forgot to double it..

Answer 6

418
