Question

Pls show work. 3.14 for pi

Answer 1

The easiest way to do this is to split each figure into smaller shapes.  
1. a rectangle and a triangle
2. 3 separate rectangles
3. triangle and rectangle
... so on
You then find the areas of the smaller shapes and then add them together.
1. (for rectangle) 6*3 = 18
    (for triangle) (12*15)/2 = 90         90 + 18 = 108
2. 4*8 = 32
    8*4 = 32
    12*12 = 144           32 + 32 + 144 = 208
...so on
