what is the area of this figure
if you can't tell im not smart please help

For this case, we must find the area of the figure composed of a parallelogram and a right triangle.
Let:
a: Base
h: Height
The area of the triangle is given by:
[tex]A = \frac {b * h} {2}\\A = \frac {20 * 8} {2}\\A = \frac {160} {2}\\A = 80 \ in ^ 2[/tex]
The area of the parallelogram is given by:
[tex]A = b.h\\A = 20 * 16\\A = 320 \ in ^ 2[/tex]
The total area is given by the sum of the areas:
[tex]At = (80 + 320) in ^ 2\\At = 400 \ in ^ 2[/tex]
Answer:
[tex]400 \ in ^ 2[/tex]
