Area of an Equilateral triangle = \(\frac{\sqrt{3}a^2}{4}\)
where, a = side of an Equilateral triangle
Put, \(a = 6\) to get Area = \(9\sqrt{3}\)
Hence, option B

I have always thought of the Area of Eq Tri as (Base/2)*(Base/2)*√3. Same formula in the end, but easier for me to remember. Hope it helps!
