Question

Find the scale factor that was used to create the dilation below

Answer 1

To calculate the scale factor we will divide the sides of the rectangle.

$\frac{XY}{X^{\prime}Y^{\prime}}=\frac{18\operatorname{cm}}{12\operatorname{cm}}=1.5$

The scale factor would be 1.5 to go from rectangle XYWZ to X'Y'W'Z'.
