Find the area of a triangle with an apothem of 3.3 ft.

2 answers

Area of a polygon with n sides is given by
Area = na/2
where n=number of sides of polygon
a=apothem.

For a triangle, n=3.
Actually, the equation is ap/2, where a = Apothem and p = perimeter. You know the apothem, so you need to use special right triangles (specifically 30-60-90) to find it.
