Okay. So there's two triangles and three rectangles. 
Do you know the formulas for the areas of a triangle, and a rectangle, respectively?$$A_{triangle}=?$$$$A_{rectangle}=?$$

It's okay if you don't, I can tell you.
I just want to see how much you know so we can start from there :)

Actually, the area of a triangle is bh/2, because it's half of a square:|dw:1458940163516:dw|
