___________________________

➠ Given :

Side of an equilateral triangle is 2√3 cm.

____________________________

➠ To Find :

We have to find the area of the equilateral triangle.

____________________________

➠ Solution :

We know the formula to find the area of the equilateral triangle.

$\Large{\boxed{\boxed{\sf{Area = \frac{\sqrt{3}}{4} \times (Side)^2}}}}$

$\sf{\implies Area = \frac{\sqrt{3}}{4} \times (2\sqrt{3})^2} \\ \\ \sf{\implies Area = \frac{\sqrt{3}}{\cancel{4}} \times \cancel{12}} \\ \\ \sf{\implies Area = \sqrt{3} \times 3} \\ \\ \sf{\implies Area = 3\sqrt{3}} \\ \\ \sf{\therefore \: Area \: of \: equilateral \: triangle \: is \: 3\sqrt{3} \: cm^2}$
