Answer 1a 18 1b 36 1c 648
 1a : if you look at the shape you will see its made of squares. I counted the squares, its 18. 
1b : one side is 6 in. since its a square all sides are equal. so multiply 6 by 6 to get 36.
1c : this one is easy. We take the number of squares across the surface (18) by the area of each square (36) it is 648.
Also sorry I didn't make this clearer earlier.
