Use the image to answer the question.
An illustration shows two rectangles. The first is horizontally positioned lengthwise and the second is positioned slanting lengthwise to the left. The first rectangle has a base length of 5 inches and vertical width of 3 inches. The tilted second rectangle has a length of 9 inches and a width of 5.4 inches.
What scale factor was used to enlarge the rectangle in the image? The measurements refer to inches. Give your answer as a decimal.

To find the scale factor used to enlarge the second rectangle, we can compare the corresponding sides of both rectangles.
The original rectangle has a base length of 5 inches, while the enlarged rectangle has a length of 9 inches.
Therefore, the scale factor used to enlarge the rectangle is 9/5, which simplifies to 1.8.
So, the scale factor used to enlarge the rectangle in the image is 1.8.
