Question 1017819
An exterior angle of a regular polygon measures 18 degrees. How many sides does the polygon have? If the length of the side of the polygon is 2 units, what is the area of the polygon? There are 20 sides just need help on the last part. 
---------------
360/18 = 20 sides.
-------------------------------
{{{Area = ns^2*cot(180/n)/4}}} where n = # of side and s = side length
{{{Area = 20*4*cot(9)/4}}}
=~ 126.275 sq units
