Question

Triangle abc and def are similar such that 2ab=de and bc=8 cm, then ef is

Answer 1

As they are similar and according to given information 2ab=de
2bc = ef
so ef = 16

Answer 2

Answer:

given : ∆ABC ~ ∆DEF

DE = 2AB and BC = 8 cm

therefore, AB/DE = BC/EF

=> AB/2AB = 8/EF [since, DE=2AB]

=> 1/2=8/EF

therefore , EF= 16 cm
