Find the area of a polygon in square units

To find the area of a polygon in square units, you can use the formula:

Area = 0.5 * n * s * a

Where:
- n is the number of sides of the polygon
- s is the length of each side
- a is the apothem (the perpendicular distance from the center of the polygon to a side)

You may also use the formula:

Area = 0.5 * n * s * r

Where:
- n is the number of sides of the polygon
- s is the length of each side
- r is the radius of the circumcircle of the polygon

Simply plug in the values of n, s, and a or r into the appropriate formula to find the area of the polygon in square units.
