Answer:
54 cm squared
Step-by-step explanation:
For the top square, it is 3 times 3 which is 9. For the middle rectangle, we do 5 times 3 which gives us 15. For the bottom rectangle, we do 10 times 3 which gives us 30. So we add 9, 15, and 30 which gives us 54. I hope this helps and please mark me brainliest!
