Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!

Step-by-step explanation:
Hi there!
![\displaystyle\frac{2}{3} (6x+30)=5(x+4)-2x](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B2%7D%7B3%7D%20%286x%2B30%29%3D5%28x%2B4%29-2x)
Distribute 2/3 and 5 into the parentheses:
![4x+20=5x+20-2x](https://tex.z-dn.net/?f=4x%2B20%3D5x%2B20-2x)
Combine like terms:
![4x-5x+2x=20-20\\-x=0\\x=0](https://tex.z-dn.net/?f=4x-5x%2B2x%3D20-20%5C%5C-x%3D0%5C%5Cx%3D0)
