Answer:
The actual length of the wall is 43.2 feet.
Step-by-step explanation:
This is because a 12 foot tall wall is 2.5 inches. We divide 12 by 2.5 and get 4.8. This means that each inch is equal to 4.8 feet. If the second wall is 9 inches tall, you multipy 4.8 by 9 and get 43.2 feet as you final answer.
Let me know if you need any more help. Have a nice day. :)
