Equilateral triangle inscribed in a circle, has got centre of the circle where all medians
intersect.
Medians of equilateral triangle, intersect at a point which divides every median in
the ratio 2:1.
Where part towards the vertex is 2 units and the part towards the side is 1 unit.
Area of equilateral triangle =√34 side^2 =9√3=√34
In the given equilateral triangle Median/ Altitude / Height of equilateral triangle = √3/2 (𝑠𝑖𝑑𝑒) = √3/2 (6)
Median = 3 √3
If we split 3 √3 , in the ratio 2:1.
It is 2 √3 :1 √3.
So, if we look at the figure part towards upper vertex is 2 √3 units.
Hence a = 2 √3 .
