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

Answer 1

To find the scale factor, we can divide the corresponding side lengths of the small square and the big square.

For the length of the side, we have (5.4 in) / (3 in) = 1.8.

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