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.
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.
