△CDE ~ △PQR. CD = 9m, EC = 15m, PQ = 15m. What is the length of RP?

Answer 1

Since the two triangles are similar, we can set up a proportion to find the length of RP:

CD/EC = PQ/RP
9/15 = 15/RP

Cross multiplying, we get:
9*RP = 15*15
9RP = 225
RP = 225/9
RP = 25

Therefore, the length of RP is 25m.
