#A regular polygon has n number of sides. Each side has length s.

#The area of a regular polygon is: (0.25*n*(s^2)) / (tan(pi/n))
#The perimeter of a polygon is: length of the boundary of the polygon
#Write a function called polysum that takes 2 arguments, n and s. 
#This function should sum the area and square of the perimeter of the regular polygon. 
#The function returns the sum, rounded to 4 decimal places.
