The perimeter of any regular n-gon of side length x is equal to nx. Therefore, the perimeter of a 13-gon (a triskaidecagon) of side length 2.3 centimetres is equal to 13 x 2.3 = 29.9 centimetres.
A pentagon has 5 sides. A regular pentagon has sides of all the same length. So a regular pentagon of side 5cm has a perimeter of 5 x 5cm = 25cm.
Assuming a regular ten-sided shape, of which every side is the same length, each side will be 114/10 = 11.4 centimetres.
Assuming the shape is a regular dodecagon, with 12 angles and lengths the same, a dodecagon with sides of 9.25 centimetres has a perimeter of 9.25 x 12 = 110 centimetres.
If the permiter of a regular octagon is 8z-16, then the length of each side would be the perimeter / 8 or 2z-2
Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
The perimeter of a regular pentagon is five times the side length.

If a polygon with a perimeter of 30 centimeters has sides with length 6 cm/side, then it has 30 cm / 6 cm per side = 5 sides. So a regular pentagon with a side length of 6 cm has a perimeter of 30 centimeters.
It is: 24/6 = 4 cm
If each side is 1cm long then its perimeter is 8 times 1cm = 8 centimeters
A hexagon has six sides, and if it is regular then all the sides are the same length (in this case, 6cm). The perimeter is the total distance around the shape, so if each side if 6cm and there are six sides, then the perimeter will be 6x6cm, or 36cm.
A pentagon has 5 sides. A regular pentagon has sides of all the same length. So a regular pentagon of side 5cm has a perimeter of 5 x 5cm = 25cm.
It depends how big it is. But the rule is: Side length x 8 = Perimeter. For example, if one side was eleven centimeters long then the perimeter would be P= 11 x 8. It would be eighty-eight centimeters. Note: This rule only works for regular octagons. If you need to find the perimeter of an irregular octagon, then you have to measure each side and add up the measurements of each side.
A regular octagon has a sum of 1080 degrees for all angles, 1080 degrees divided by 8 angles is 135 degrees per angle. The perimeter is 200 centimeters divided by 8 sides is 25 centimeters.
Area = (side)2 = 16 square centimeters Perimeter = 4 x side = 16 centimeters
The perimeter of a square with a side of length 4.76 centimeters is: (4 sides x 4.76) = 19.04 cm
Six cm per side.
