The Length of PQ such that Triangle JKL is similar to Triangle PQR ~

To make the given triangles similar, we have to get the ratios of each of their corresponding side to be equal to one another.

That is :

[tex]\qquad \sf  \dashrightarrow \: \dfrac{PQ}{12} = \dfrac{9}{6} [/tex]

[tex]\qquad \sf  \dashrightarrow \: PQ = \dfrac{9}{6} \times 12[/tex]

[tex]\qquad \sf  \dashrightarrow \: PQ = {9}{} \times 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: PQ = 18 \: units[/tex]

hence, the option C is correct
