Pentagon means five sides. If one side is 4cm, then the perimeter which is the total length of all the sides is 4cm multiplied by 5 equals to 20 cm.
If the permiter of a regular octagon is 8z-16, then the length of each side would be the perimeter / 8 or 2z-2

21*9 = 189 feet.
A regular nonagon has 9 sides and so its perimeter is 9*40 = 36 units of measurement
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
40
It is: 162/9 = 18cm
For any nonagon in general:Perimeter = (side-1 + side-2 + side-3 + . . . . . + side-8 + side-9)For a regular nonagon:Perimeter = 9 x (length of one side)
One possibility is an irregular triangle with a side of 5 units.
8
Each side is 117/9 = 13 cm
25
Area of a regular polygon = 1/2(apothem)(perimeter) 2025 = 1/2(25)(perimeter), so the perimeter = 2025 divided by 25/2. Perimeter = 162 Side length = 162/9 Side length = 18
I think you mean a regular nonagon. This is a nine-sided polygon. If you have the length of one side, you can multiply it by 9 to find the perimeter of all sides.
