Each side is 117/9 = 13 cm
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
If it is a regular nonagon then it has 9 equal sides, so all you needed to do was divide 31.23 by 9. (You would have got 3.47 cm)
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
It is a nonagon in which all the sides have the same length. This should not be confused with a regular nonagon which also requires all angles to be the same.
The perimeter of a regular hexagon with a side length of 6.8mm is 40.8mm

It is: 162/9 = 18cm
If it is a regular nonagon then it has 9 equal sides, so all you needed to do was divide 31.23 by 9. (You would have got 3.47 cm)
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.
One possibility is an irregular triangle with a side of 5 units.
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)
Add the length of all nine sides up.
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.
It is a nonagon in which all the sides have the same length. This should not be confused with a regular nonagon which also requires all angles to be the same.
The perimeter of a regular hexagon with a side length of 6.8mm is 40.8mm
If the side length is 7, the perimeter is 35.
