What are the side lengths of [math]{\bigtriangleup}D{^\prime}E{^\prime}F{^\prime}[/math] with a scale factor of [math]2.5[/math] given the preimage and image below and the information that [math]DE = 1[/math], [math]EF = 9.2[/math], and [math]FD = 8.6[/math]?

[list=1][br][*]Choose a side to start with and multiply the scale factor ([math]k[/math]) by that side length.[br][*]Choose a second side and multiply the scale factor by that side length.[br][*]Choose the last side and multiply the scale factor by that side length.[br][*]Label the figure with the side lengths.[br][/list][br][br]This applet is provided by Walch Education as supplemental material for their mathematics programs.
