If the side length is 7, the perimeter is 35.

Only if you know what kind of polygon you have. If you know that you have a hexagon and one side is 1 cm, the perimeter is 6 cm. You only have to know the length of one side, since a regular polygon has equal sides. Perimeter or a regular polygon is the length of each side times the number of sides. You need to know both pieces to find the perimeter. ■

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.

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]

Area of regular polygon: 0.5*apothem*perimeter

If the polygon has n sides, then the perimeter is 2.75*n metres.

A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.

If the side length is 7, the perimeter is 35.

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.

The answer depends on what information you have about the regular polygon. You need to know, or be able to derive, the number of sides (n) and the length of each side (L). Then the perimeter is n*L units of length.
