We can find the factor of dilation by finding the ratio between two correspondent sides of the quadrilaterals.

Consider Q'R' and QR.

$\begin{gathered} QR=6 \\ Q^(\prime)R^(\prime)=2 \\ \Rightarrow(Q^(\prime)R^(\prime))/(QR)=(2)/(6)=(1)/(3) \end{gathered}$

Therefore, the scale factor for the dilation is equal to 1/3
