Question

In Fig. 6.15, if Δ ABC ~ Δ DEF and their sides are of lengths (in cm) as marked along them, then find the lengths of the sides of each triangle.

Answer 1

Solution: Δ ABC ~ Δ DEF (Given)

Therefore, AB = 2 × 5 –1= 9, BC = 2 × 5 + 2 = 12,

CA = 3 × 5 = 15, DE = 18, EF = 3× 5 + 9 = 24 and FD = 6 × 5 = 30

Hence, AB = 9 cm, BC = 12 cm, CA = 15 cm,

DE = 18 cm, EF = 24 cm and FD = 30 cm.

What if i only solved till x=5. It was a 3 marker question. How many will i get?
