help i need the answer e

Answer:
600 [tex]cm^2[/tex]
Step-by-step explanation:
In order to find the area of this shape, we need to break it down into a triangle and a square
The length and width of the square are 20 cm
[tex](20)(20)=400[/tex]
And the length and height of the triangle are 20 cm
[tex]\frac{1}{2} (20)(20)=200[/tex]
Now that we have the area of each shape, we just need to add them together to find the total area
[tex]400+200=600[/tex]
