Answer: 252 ft²
Step-by-step explanation:
The drawing's dimensions are given to be 7 cm in length, and 4 cm in width. Those values are multiplied by 3 to get the scaled drawing. This gives us 21 feet and 12 feet. When you multiply 21 feet by 12 feet, you get 252 ft². DO NOT FORGET to put the ² in the final answer.
