Answer 2

Exactly, that's all you have to do.

Answer 3

A. 10.5 units^2
B. 15.5 units^2
C. 17 units^2
D. 19.5 units^2

Answer 4

probably it's 17 unit^2
I THINK the idea is to imagine that you fill some gaps with extra areas in other places.
that led me to visualize: 3*3 square in quad2, 2*3 rectangle in quad1, and 2*1 rectangle in quad 3
so 3*3+2*3+2*1 =17 unit^2

I'll try it, but I also have to finish the rest before I know if it is right or wrong, I get back to you later.
