It is the sum of the lengths of the nine sides of the nonagon.
A regular nonagon has 9 sides and so its perimeter is 9*40 = 36 units of measurement
It is: 162/9 = 18cm
9 * 10.2 = 91.8 centimetres.
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.
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.

You add together the lengths of the nine sides of the nonagon.

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.
Add the length of all nine sides up.
