Is it right to see the hexagon as made of six equilateral triangles each of area $$\frac{8*4sqrt(3)}{2} = 16sqrt(3)$$ so that the area of the hexagon is six times the area of a triangle, i.e. $$6*16sqrt(3)=96sqrt(3)$$?

Could you please explain why you assumed that fact about hexagon while it's not given?

The fact that is not mentioned in the stem or elsewhere, then nothing avoid you to make this assumption about the hexagon and triangles.

It is just another way to solve the problem. The lesson you might learn from this is that flexibility in quant solving problem is king.

Thanks Carcass. So can we make the same assumption a bout all regular polygons n (number of sides)>3?
