Which scale factor was used to enlarge the rectangle in the image the measurements refer to inches, give your answer as a decimal. The first rectangle has 3 inches on one side and 5 inches on the long side. The other rectangle has 5.4 inches on one side and 9 inches on the long side.

Answer 1

To find the scale factor, we need to divide the corresponding lengths of the two rectangles.

For the short side, the scale factor is calculated as:

$The\ scale\ factor = \frac{5.4\ inches}{3\ inches} \approx 1.8$

For the long side, the scale factor is calculated as:

$The\ scale\ factor = \frac{9\ inches}{5\ inches} = 1.8$

Therefore, the scale factor used to enlarge the rectangle in the image is approximately 1.8.
