Answer 1

Answer: 4:1( PLS MARK BRAINLIEST IF IT HELPS)

Step-by-step explanation:

We know that area( equilateral triangle)= √3a²/4

If each side of tri ABC = 2a unit

Then, Area (triABC) = √3 a² ……….. (1)

Now, BD = BC/2 ( given)   => BD = 2a/2 = a

So, area( equilateral triangle BDE)=√3a²/4 ….(2)

By dividing (1) by (2)

ar( tri ABC) / ar(tri BDE) = (√3a²*4)/ √3a² = 4/1  = 4 : 1
