Solve the following problem by using the method of squaring the scale factor. Giselle makes a scale drawing of a rectangle that measures 4 inches in length and 3 inches in width. Her scale drawing measures 6 inches in width. Which equation can she use to find the area of the scale drawing in square inches?

Question

A. 2 with power of 2 * 12 = 48
B. 2 with power of 2 * 24 = 96
C. 2 * 12 = 24
D. (1/2) with power of 2 * 12 = 3

Answer 1

The correct equation that Giselle can use to find the area of the scale drawing in square inches is:

B. 2 with power of 2 * 24 = 96

This is because the scale factor for the length is 6/4 and the scale factor for the width is 6/3. When you square the scale factor of the width (6/3)^2, you get 4, which is then multiplied by the original area of the rectangle which is 24 square inches.
