Question

If the rectangle below is enlarged using a scale factor of 1.5, what will be the area of the new rectangle?

Answer 1

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
