JKL is similar to PQR
so they want PR
JK
L is similar to
PQ
R
So PR is similar to JL
And they also give us the sides KL and QR
J
KL is similar to P
QR
Both of those sides are similar, so we can form a proportion.

Plug in the numbers:

Cross multiply:

Isolate PR

Simplify it

So your final answer is
