ABC and BDE are two equilateral triangles such that D is the midpoint of BC. Ratio of the areas of triangles ABC and BDE is
Δ ABC and Δ BDE are two equilateral triangles
Let a be the side of Δ ABC
Since D is midpoint of BC
So the side of equilateral ΔBDE = 
Area of equilateral Δ = 
(side)2
Area of Δ ABC = 
………….1
Area of Δ BDE = 
= 
Putting value of 
× 
…………from 1
Area of Δ BDE = 
Area of Δ ABC
=
