Triangle CDE is similar to triangle PQR.

CD= 9m, EC = 15m, PQ =15 m. What is the length of RP

Since triangle CDE is similar to triangle PQR, we can write the following proportion involving their corresponding side lengths:

CD/EC = PQ/RP

Substituting the known values, we have:

9/15 = 15/RP

Simplifying the equation, we get:

9RP = 15 * 15

9RP = 225

Dividing both sides by 9, we get:

RP = 225/9

RP = 25 m

So, the length of RP is 25 meters.
