Question

ifABC and BDE are two equilateral triangle such that d is tge mid point of bc then find ar(abc):ar(bde)

Answer 1

This will help you. In case of any query ask me

Answer 2

As both ABC and BDE are equilateral triangle so triangle ABC is similar to triangle BDE and we know that ratio of are of two similar triangle is directly proportional to the ratio square of their sides

so,

ar(ABC)/ar(BDE) =BC*BC/BD*BD

so ar(ABC) : ar(BDE) = 4 : 1
