(10, 16, 18, 21)

1b. Each square has an area of |___| in².
(6, 12, 24, 36)

1c. So, the surface area of the figure is |___| in².
(54, 324, 576, 648)

Answer 1

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.
