Question

Given two triangles, ABC and DEF such that ABC similar to DEF and their areas are 81 cm and 144 cm
respectively. If EF = 16 cm, then find BC.

**URGENT**​

Answer 1

∆ABC ~ ∆ DEF....... given

ABC² = BC²

DEF² EF²

81 = BC

144 16

9 = BC

12 16

12BC = 9× 16

12BC = 144

12BC = 144

BC = 144/12

BC = 12cm
