Question

Line segment LM is dilated to create L'M' using point Q as the center of dilation and a scale factor of 2.What is the length of segment QM'?

Answer 1

To calculate the distance from the center of dilation, we shall multiply the scale factor by the distance fom the corresponding length on the pre-image.

This means;

$\begin{gathered} QM^{\prime}=2\times QM \\ QM^{\prime}=2\times3 \\ QM^{\prime}=6 \end{gathered}$

ANSWER:

The length of QM' is 6 units
