Please answer a.s.a.p, course work needs to be in for tomorrow!!!
The general area of any polygon can be expressed by this equation:
$\displaystyle A=\frac{nx^2}{4\tan{(\frac{180}{n})}}$
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.
