Question

Shapes ABCDE and JKLMN are similar, but not necessarily drawn to scale.What is the value of q and r

Answer 1

As the figure ar similar, we have that

$\frac{20}{8}=\frac{q}{7}=\frac{r}{5}$

Therefore

$q=7\cdot\frac{20}{8}=\frac{35}{2}=17.5$

and

$r=5\cdot\frac{20}{8}=\frac{25}{2}=12.5$

so the answer is the second option
