# Area of an Equilateral Triangle

How to find the area of an equilateral triangle: formula, example, and its solution.

## Formula

*A* = (√3/4)⋅*a*^{2}*A*: Area of an equilateral triangle*a*: Side of an equilateral triangle

## Example

The equilateral triangle's side is 6.

Then *A* = (√3/4)⋅6^{2}.

6^{2} = 36

36/4 = 9

So *A* = 9√3.
