Given that the area of an equilateral triangle is 234 cm2, find its perimeter.
---------
Area = b*h/2 = 234
h = b*sqrt(3)/2
----
Solve for b
P = 3b

In terms of the length of a side, s, the area of an equilateral triangle is

A+=+%28s%5E2%2Asqrt%283%29%29%2F4

Given the area of 234, solve

%28s%5E2%2Asqrt%283%29%29%2F4+=+234

to find the length of a side; then of course the perimeter is 3 times that length.
