The area of an n-sided regular polygon with length of side t is equal to:
nt2 / (4 tan(180 / n))
Taking a simple example, if a square (n = 4) has sides of 2 inches (t = 2):
4 x 22 / (4 tan (180 / 4)) = 4
Therefore, the area of a square with 2 inch sides is 4 inches. Upon completion of the sum, don't forget to include the units of measure at the end.

The area of a four-sided polygon is base times height.
An n sided polygon has n*(n-3)/2 diagonals.
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
The sum of the internal angles of a n-sided polygon is (n-2) x 180o. For a 17-sided polygon, n = 17 and the sum of the angles is (17-2) x 180o = 2700o
There are: (n-2)
