Question

Abc and bde are two equilateral triangles such that d is the midpoint of bc. find the ratio of the areas of triangles abc and bde.

Answer 1

Here,
ABC is divided into two congruent triangle

Because
All the sides are equal,
So 2 divided triangle are congruent...

Now
Ar(ABC) = ar(abd) + ar ( BDE)
Ar(ABC) = 2ar(BDE)
If area of triangle =1
Then

1 = 2(1)
1 = 2
1/2=0

So,
The ratio = 1/2
