9 * 10.2 = 91.8 centimetres.
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
add all the sides ???
The perimeter is just the total length of the sides so 5 x 6 = 30 inches.
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
Add the length of all nine sides up.
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)
No
It would be 32.8 centimeters. A square has 4 sides and equal sides. So 8.2 x 4 equals 32.8
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
add all the sides ???
Five times the length of one of the sides.
A nonagon has nine sides.
