Question

Even answering one is huge for me please help.

Answer 1

I am not sure if it's correct but for 20) I think it is 150

Explanation:

First to find the area of the triangle is base times height divided by 2. So 12×8=96 then 96÷2=48

For the rectangle is 12×7=84

For the little square is 6×3=18

If you add them all together it would be 150
