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
In a regular nonagon there are 9, if its irregular its dependant.
It is: 162/9 = 18cm
9 * 10.2 = 91.8 centimetres.
A nine sided nonagon is only a regular shape if it has 9 equal sides
It is the sum of the lengths of the nine sides of the nonagon.
90
You add together the lengths of the nine sides of the nonagon.
nonagon
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 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.
A regular nonagon.
In a regular nonagon there are 9, if its irregular its dependant.
It is a nonagon. It need not be a regular nonagon.
Add the length of all nine sides up.
189 feet.
