Answer :

Notice the correspondence between the vertices of the polygons:

[tex]VQRGX\approx CNPMS[/tex]

Corresponding segments of similar polygons are proportional. Then:

[tex]\frac{CS}{VX}=\frac{PM}{RG}[/tex]

Substitute VX=48, PM=22 and RG=16.5 and solve for CS:

[tex]\begin{gathered} \Rightarrow\frac{CS}{48}=\frac{22}{16.5} \\ \Rightarrow CS=\frac{22}{16.5}\times48 \\ \Rightarrow CS=64 \end{gathered}[/tex]

Therefore, the length of CS is 64.
