How do you find the area of a regular polygon if you are only given the apothem? I have several problems but I'm only given the apothem, and I'm not sure how to find the perimeter.

Question

ranga · Answer

If you know the number of sides of the regular polygon you can find the internal angles and you can figure out the length of the side using the apothem.  You can also find the area of that one triangle.  Multiply by the number of triangles and you will get the area of the polygon.
