2. 72 square feet
3. 31.5 square feet
Step-by-step explanation:
For the first one use the equation A=bh.

Solve: A=64
For the second one multiply 8*3 which gives you 24. Next multiply that by 3 to give you 72 square feet.
For the third one multiply 9 by 3.5 to get 31.5 square feet.
Yes put that as an answer
