The distance from the center of a regular polygon to a side is called its apothem(a). Keep that in mind. The perimeter(p) of the polygon is the measurement of all its sides, or the measurement of one side x the number of sides when it comes to a regular polygon.To find the area of the polygon, use the following e formula.Area = 1/2 (a) x (p)You must use the full perimeter.

Example: To find the perimeter of a rectangular box, with length as 6cm and Breadth as 4 cm, we need to use the formula, Perimeter of a Rectangle = 2 (L+B) = 2 ( 6 cm + 4 cm) = 2 × 10 cm = 20cm.
To find the circumference (distance around) of a circle, use the formula pi x d (d=diameter)
2(2x) +2x = 100
