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

`(20)/(8)=(q)/(7)=(r)/(5)`

Therefore

`q=7\cdot(20)/(8)=(35)/(2)=17.5`

and

`r=5\cdot(20)/(8)=(25)/(2)=12.5`

so the answer is the second option
