Since the 15-gon is regular, each side measures the quotient of the perimeter divided by the number of sides.


The area is given by *[tex \LARGE A\ =\ \frac{1}{4}nt^2\cot\left(\frac{\pi}{n}\right)]


Where *[tex \LARGE t] is the measure of one side and *[tex \LARGE n] is the number of sides]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
