Answer 2

Answer:

10 cm

Step-by-step explanation:

Given, ΔABC ~ ΔQRP.

Given, BC = 15 cm and AB = 18 cm.

∴ (area of ΔABC)/(area of ΔQRP) = (BC²)/(RP)²

⇒ 9/4 = (15)²/(RP)²

⇒ 9/4 = 225/(RP)²

⇒ 9(RP)² = 225 * 4

⇒ (RP)² = 900/9

⇒ RP² = 100

⇒ RP = 10 cm.

Therefore, the value of RP = 10 cm.

Hope it helps!
