Answer» Match the following columns:

Column I	Column II
(a) In a given ∆ABC, DE ∥ BC and $\frac{A D}{D B} = \frac{3}{5} .$ If AC = 5.6 cm, then AE = ...... cm.	(p) 6
(b) If ∆ABC ∼ ∆DEF such that 2AB = 3DE and BC = 6 cm, then EF = ...... cm.	(q) 4
(c) If ∆ABC ∼ ∆PQR such that ar(∆ABC) : ar(∆PQR) = 9 : 16 and BC = 4.5 cm, then QR = ...... cm.	(r) 3
(d) In the given figure, AB ∥ CD and OA = (2x + 4) cm, OB = (9x − 21) cm, OC = (2x − 1) cm and OD = 3 cm. Then x = ?	(s) 2.1
