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 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

- Area of a triangle base on the base and height
- Area of a triangle using two sides and the interior angle.
- Area of a triangle using two angles and the interior side.
- Area of a triangle using three known sides.
- Area of Equilateral Triangle
- Area of a triangle defined by three points (x,y) in a plane.
- Height of a triangle based on the area and base
- Interior Angle of a triangle based on the length of three sides
- Semi-perimeter of a triangle
- Area between two vectors
- Compute the Distance Between a Point and a Line
- Compute the area of a triangle defined by three points
- Compute the distance between two points
- Compute the slope intercept form of a line from two points
- Compute the mid-point between two points
