the area of an equilateral triangle is 36cm^2

Each side is x

Find the value of x

I tried

bh*1/2=36

but that just ends up cancelling everything. What do I do?

It looks like x=1 but I'm not sure :/

But in an equilateral triangle, (from pythagoras' theorem)

Sub in your formula:

You should be able to solve for the length of the base now. :) - May 31st 2010, 10:50 AMMukilab

Come on, it's not difficult. :)

Then take square root on both sides to get the length of the base, which is also equal to x.
