the area of a regular polygon is 360 square cm. If the apothem is 9 cm and one side measures 16 cm, how many sides does this polygon have?
-----------
Area using side length:
Area = ns^2*cot(180/n)/4
For n = 4, Area = 256
For n = 5, Area = 440.44
---------------
The area increases with n, so there is no integral solution.
