The Area of an Equilateral Triangle calculator computes the area of a triangle given the length of the sides.

INSTRUCTIONS: Choose units and enter the following:

• (s)  Length Sides.

Area (A): The calculator returns the area in square meters (m²).  However, this can be automatically converted to other area units (e.g. square feet) via the pull-down menu.
