The scale factor is calculated by dividing the corresponding side lengths of the enlarged rectangle by the original rectangle.
For the length, the scale factor is given by 9 in. (from box two) divided by 9 in. (from box one) = 1.
For the width, the scale factor is given by 3 in. (from box two) divided by 5.4 in. (from box one) ≈ 0.5556.
Therefore, the scale factor used to enlarge the rectangle in the image is approximately 1 for the length and 0.5556 for the width.
