Two similar triangles, $$\triangle {ABC}$$ and $$\triangle {JKL}$$ are shown. ![](http://admin.getprephub.com/media/editor/g10_20230225201752197984.png) What is the length of side $$JL$$ ?

Given that, $$\triangle {ABC} \sim \triangle J K L$$ Therefore, $$\frac{A B}{J K}=\frac{B C}{K L}=\frac{A C}{J L}$$ Putting the values, $$\frac{3.5}{10.5}=\frac{5}{15}=\frac{2.5}{J L}$$ Or, $${JL}=\frac{2.5 \times 10.5}{3.5}=7.5$$
