Question

if triangle ABC similar to triangle DEF that is BC is equals to 3 cm FE is equals to 4 cm and area of triangle ABC is equals to 54 CM determine the area of triangle DEF...???

Answer 1

∆ ABC is similar to ∆ DEF...

So,

(area of ABC)/(area of DEF)

= (BC/FE)^2

SO,

54/area of DEF = 9/16

Thus, area of DEF

= 96 cm^2
