how do you express the area of an equilateral triangle as a function of
a)the length of each side (l)
b)the altitude (h)
i have no idea how to work this out..so any help would be greatly appreciated
thanks guys=]

altitude of a an equilateral triangle = $\displaystyle side * \sqrt{3}/2$
use trigonometry or geometry(Pythagoras theorem) to prove above thing
