If ΔABC∼ΔQRP,ar(ΔABC)ar(ΔPQR)=94, AB = 18 cm and BC = 15cm, then PR is equal to(A) 10 cm(B) 12 cm(C) 203 cm(D) 8cm

If ΔABC∼ΔQRP,ar(ΔABC)ar(ΔPQR)=94, AB = 18 cm and BC = 15cm, then

1.	If ΔABC∼ΔQRP,ar(ΔABC)ar(ΔPQR)=94, AB = 18 cm and BC = 15cm, then PR is equal to(A) 10 cm(B) 12 cm(C) 203 cm(D) 8cm
Answer» If $Δ A B C \sim Δ Q R P, \frac{a r (Δ A B C)}{a r (Δ P Q R)} = \frac{9}{4}$ , AB = 18 cm and BC = 15cm, then PR is equal to (A) 10 cm (B) 12 cm (C) $\frac{20}{3} c m$ (D) 8cm
