EQUILATERAL TRIANGLE AREA: Solve for the Area of An Equilateral Triangle

An equilateral triangle is a triangle with three (3) equal sides. The following is the illustration and formula on how to solve for the area of the equilateral triangle.

I also have several PHP and Java codes here related to solving for the area of a square, area of circle, area of a triangle, area of rectangle and area of an ellipse.

Formula

A = Area of the equilateral triangle
a = one side of the triangle

PHP Code

<?php
$a=7;
$area=sqrt(3)/4*pow($a,2);
echo "The area of the equilateral triangle with the side of $a is ".number_format($area,3);?>

Output
