Question

A book is 6 inches wide and 9 inches tall. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. A publisher wants to use a scale factor of 1.5 to enlarge a book. What will the area of the front of the book be after the book is enlarged? 54 in2 81 in2 121.5 in2 78.75 in2

Answer 1

To figure this out, you would find the area of the book by doing 9 * 6, which is 54. Now what you do is multiply that by 1.5 since that is the scale factor, and you get 81 in²

Answer 2

 The first step is to enlarge 6 inches.   6 inches enlarged by 1.5 = 9 inches
 Then 9 inches.                                  9 inches enlarged by 1.5 = 13.5 inches


 Next, you multiply to find the area.    area = 9 × 13 = 121.5 square inches
