What scale factor was used to enlarge the rectangle in the image? The measurements refer to inches. Give your answer as a decimal.

To determine the scale factor, we can compare the lengths of two corresponding sides of the rectangles.

Let's compare the lengths of the longer sides of the original and enlarged rectangle.

In the original rectangle, the longer side measures 3 inches.
In the enlarged rectangle, the longer side measures 6 inches.

To find the scale factor, we divide the length of the longer side of the enlarged rectangle by the length of the longer side of the original rectangle:
Scale factor = 6 inches / 3 inches = 2

Therefore, the scale factor used to enlarge the rectangle in the image is 2.
