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

Answer 1

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

(CD/PQ) = (DE/QR)

Substituting the given values:

(9/15) = (15/QR)

Cross multiplying:

9 * QR = 15 * 15

QR = (15 * 15) / 9

QR = 225 / 9

QR = 25

Therefore, the length of RP is 25 m.
