Use the image to answer the question.

To find the scale factor, we can compare the corresponding sides of the original rectangle and the enlarged rectangle in the image.

For rectangle one:
Original side lengths: 3 inches and 5 inches
Enlarged side lengths: 9 inches and 5.4 inches

To find the scale factor, we can divide the corresponding side lengths of the enlarged rectangle by the original rectangle.

For the first side:
9 inches / 3 inches = 3

For the second side:
5.4 inches / 5 inches = 1.08

The scale factor for the enlargement of the rectangle in the image is approximately 3.08 (or 3.1 rounded to one decimal place).
