# Area of an equilateral triangle calculator

The formula to calculate the area of an equilateral triangle is:

**Area = (√3/4) × a²**

where “a” is the length of any one side of the equilateral triangle.

To use this formula in a calculator, you simply need to square the value of “a”, multiply it by (√3/4), and then round the result to your desired number of decimal places.

Alternatively, you can use an online area of equilateral triangle calculator to make the calculation even easier.

## Area of equilateral triangle step by step

To find the area of an equilateral triangle, you need to know its side length. Here are the steps to calculate the area of an equilateral triangle:

**Determine the length of one side of the equilateral triangle.****Square the length of one side.****Multiply the squared length by the square root of 3.****Divide the result by 4.**

The formula for the area of an equilateral triangle is:

**Area = (s^2 * sqrt(3))/4**

where s is the length of a side of the equilateral triangle.

For example, if the length of one side of an equilateral triangle is 6 cm, then the area can be calculated as follows:

**Area = (6^2 * sqrt(3))/4**

**Area = (36 * 1.732)/4**

**Area = 62.3538 square cm**
