Answer:
33cm^2
Explanation:
The easiest first step is to get the area of the square first.
3*3=9
Then, to get the area of the triangles, multiply 1/2b*h, aka 1/2(4)*3
1/2(4)=2
2*3=6
Each triangle is 6 cm^2
There are 4 triangles, so multiply 6 by 4:
24cm^2
Finally, remember that square from earlier? Add that area to the triangles'.
24+9=33
Hope this helps!
