Since the triangles △CDE and △PQR are similar, we can set up a proportion to find the length of RP.

The corresponding sides of the triangles are DE and QR.
Using the proportion:
DE/QR = CD/PQ

Substituting the given values:
9/QR = 15/15

Cross-multiplying:
9(15) = QR

QR = 135

Therefore, the length of RP is 135 meters.
