Question 434377
By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:

 {{{A=S^2N/4tan((pi)/N)}}} 

where {{{S}}} is the length of any side, {{{N}}}  is the number of sides, 
{{{pi}}} is approximately {{{3.142}}}, and tan is the tangent function calculated in radians
