Equilateral

You tell us the area. - April 16th 2008, 07:34 PMstellina_91
Area = 1/2bh

= 1/2 x 2b x a

I have no idea, I'm sorry!(Crying) - April 16th 2008, 07:40 PMTKHunny

What are you not getting? You have it. Simplify and you are done.

Do you see that it is equilateral? - April 16th 2008, 07:46 PMIsomorphism

In the answer it says:

This is an equilateral triangle with a = b x root 3 and area = b^2 x root 3.

I don't know how they got this. - April 16th 2008, 07:59 PMIsomorphism
