Question 199386
<font face="Garamond" size="+2">

The area of an equilateral triangle is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ A = \frac{s^2\sqrt{3}}{4}]


Where *[tex \Large s] is the measure of one side.  You have the perimeter which is nothing more than the sum of the measures of three equal length sides.  So divide the perimeter by 3 to obtain *[tex \Large s].
