Which scale factor was used to enlarge the rectangle in the image first image was 3” x 5”. The second image was 9” x 5, 5.4” measurements refer to just give your answer as a decimal.

To find the scale factor, we can divide the corresponding sides of the two rectangles.

For the length, the first rectangle has a length of 3" and the second rectangle has a length of 9". Dividing 9 by 3, we get a scale factor of 3.

For the width, the first rectangle has a width of 5" and the second rectangle has a width of 5.4". Dividing 5.4 by 5, we get a scale factor of 1.08.

Therefore, the scale factor used to enlarge the rectangle is 3 in length and 1.08 in width.
