Answer:
The answer is 528cm^2
Step-by-step explanation:
20 * 9 = 180
Since there are two rectangles both 20 * 9 you have to multiply 180 by 2
180 * 2 = 360
Middle Rectangle: 6 * 20 = 120
Triangles: .5 * 8 * 6 = 24
Since there are two triangles both measuring the same you must multiple the area of the triangle by 2
24 * 2 = 48
Finally, 360 + 120 + 48 = 528
