The perimeter of a polygon is the distance around the outside of the polygon. A polygon is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units.To find the perimeter of a polygon, take the sum of the length of each side.

find the other side of an circumscribed polygon , 8,10,21?

The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]

Perimeter = 2*Area/Apothem.

To find the perimeter of any polygon, add up the lengths of all the sides.

Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m.

You have to add up the length of all the sides.

you find the perimeter and then you times all the sides together

The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.

A pentagon, which is a 5-sided figure, will have a perimeter equal to the sum of the lengths of all the sides. This will be true for any polygon; the perimeter of any polygon is the sum of the lengths of all the sides. If the pentagon is a regular pentagon, then the perimeter will be 5 times the length of one of the sides. For any regular polygon, the perimeter will be the length of one side times the number of sides in that polygon.

If there is regular polygon(having equal sides), then perimeter is L*N where L is length of side and N is no. of sides. If polygon is not regular then may Perimeter is equal to sum of all sides, if size of each side is known.

For the perimeter of a polygon you add the sides to find the total distance around the shape. For area, you multiply using the various formulas for different polygons.
