The area of a triangle is .5*base*height. You have a height of 3 and know what .5 is but you do not have the length of the base, so you can't do this problem. Was any other information given?

Edit: Oops, for some reason I was thinking isosceles triangle. So when you draw your apothem that divides you triangle into 2 triangles. Pick one of the two triangles--what are the angles? Since you know that one side is 3 and YOU do know the angles you can find the base.
