Question

Two rectangles are similar. The length and width of the first rectangle are 12

and 5, respectively. The length and width of the second rectangle are 14.4 and
6, respectively. The scale factor used to get from the first rectangle to the
second one is

Answer 1

scale factor = 1.2

Explanation:

To determine the scale factor, calculate the ratio of the length of the second rectangle to the length of the first rectangle. The corresponding ratio of widths should also equal the same ratio.

scale factor =
`(14.4)/(12)` =
`(6)/(5)` = 1.2
