the area of an equilateral triangle is 36cm^2
Each side is x
Find the value of x
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.
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.
