The apothem of an equilateral triangle divides the triangle into two 30-60-90 right triangles. In an equilateral triangle, the side length is times the length of the apothem.

Then find the area of the triangle using the standard formula one-half base times height:

Simplify and/or convert to decimal as required.

Note to new tutor @Istar... (if you see it)

Providing an answer with no work shown is counterproductive.

Assuming the student is interested in learning HOW to solve a problem, he now has to re-post his question, because you have done nothing to help him.

This forum is for helping students learn how to do math -- not to do their homework for them.
