Answer:
31.5 square inches
Step-by-step explanation:
First, you need to enlarge each side with a scale factor of 1.5.
7 inches = 10.5 inches
2 inches = 3 inches
The new sides are 10.5 and 3 inches long. Now, you need to use these side lengths in the area formula of a rectangle.
A = Bh
A = 10.5(3)
A = 31.5 in.²
