# Math Help - Polygon Areas

1. ## Polygon Areas

How do you find the area of a...

Pentagon
Hexagon
Heptagon
Octagon
Nonagon
Decagon

Please answer a.s.a.p, course work needs to be in for tomorrow!!!

2. The general area of any polygon can be expressed by this equation:

$A=\frac{nx^2}{4\tan{(\frac{180}{n})}}$

where n is the number of sides and x is each side's length.

For specific areas of each, do a Google search, or I would suggest looking to derive them.
