Given the information on the picture, notice that we have the following relationship between sides CA and CA' :


CA^(\prime)=k\cdot CA

where k is the scale factor.

If we use the measures given and solve for k, we have:


\begin{gathered} 10=k\cdot5 \\ \Rightarrow k=(10)/(5)=2 \\ k=2 \end{gathered}

therefore, the scale factor is k = 2
