Answer:
The area of the model on the right is 80 sq cm
Explanation:
Since the scale for the model on the left is 1 cm = 5 ft, and the scale for the model on the right is 1 cm = 2.5 ft, the area of the model on the right is 22, or 4, times larger than the area of the model on the left.
Multiply the area of the model on the left by 4 to find the area of the model on the right.
20 sq cm × 4 = 80 sq cm
