Well, you can see that WK is congruent (is that the right word?) to RN.

They even gave the measurements.

KT would be congruent to PR.

Make a ratio:

WK : RN = KT : PR

Now put in the measurements, with x as PR

14 : 24.5 = 18 : x

This will equal to 14x = 24.5 * 18.

14x = 441

x = 441/14

x = 31.5441/14 = 31.5

x = 31.5

So PR is 31.5 in.
