Given:

AB = 6 cm, DF = 16 cm and DE = 8 cm

Concept used:

When two triangles are similar, their corresponding angles are equal and their corresponding sides are proportional.

Calculation:

F3 SSC Arbaz 8-8-2023 D9

As ΔABC ~ ΔEDF

So, AB/DE = BC/DF = AC/FE

Now,

AB/DE = BC/DF

⇒ 6/8 = BC/16

⇒ BC = (6 × 16)/8

⇒ BC = 96/8

⇒ BC = 12 cm

∴ The length of BC is 12 cm.
