Question 527689
I have an equilateral triangle that I need to find the area of, but in order to find the area, I need to know the height of the triangle. I don't know how to find the height. Please help me.
--------------------
side length = s
height = any altitude
{{{h^2 = s^2 - (s/2)^2 = 3s^2/4}}}
h = s*sqrt(3)/2
-----------
{{{Area = b*h/2 = s^2*sqrt(3)/4}}}
