For number 16:
Use the vertical pencil line you have drawn to split the polygon.
12-4=8
3*8=24
12*4=24
24+24=48
48 is the area of 16
For number 17:
Split the polygon in half
Find the area of both of the parallelograms
6*20=120
6*20=120
120+120=240
The area of shape 17 is 240
(5x^2-15x) (-2x+6)
5x (x-3) -2 (x-3)
(5x-2) (x-3)
