The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
90
The area is 1583 square units, approx.
Each side is 117/9 = 13 cm
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)
The answer depends on what information you have. If you have the length of a side, then the perimeter is nine times that length.
Add the length of all nine sides up.
It is the sum of the lengths of the nine sides of the nonagon.
It is the sum of the lengths of the nine sides of the nonagon.
90
nonagon
A regular nonagon has 9 sides and so its perimeter is 9*40 = 36 units of measurement
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.
189 feet.

It is: 162/9 = 18cm
