Answer:
22.44 cm^2
Step-by-step explanation:
There's four triangles and one square so lets start with the triangles.
2.24×3÷2=3.36
That's the area of one triangle, there's four so:
3.36×4=13.44
Then the square!
3×3=9
13.44+9=22.44 cm^2
I'm not sure if this is the standard way since I didn't learn about pyramids so I used the area stuff, so sorry if its not correct.
Have a nice day!
