The Area of a Equilateral Triangle calculator computes the area of a triangle given the length the triangle's three equal sides.

INSTRUCTIONS: Choose units and enter the following:

• (a) Length of Sides

Triangle Area (A): The  calculator returns the area of the equilateral triangle in square meters.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math Science

The formula for the area of an equilateral triangle is:

`A = sqrt(3)/4   * a^2`

where

• A = area of equilateral triangle
• a = equal length of all tree sides
