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.
The answer is 28 cm.
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.
No
A square has sides of length 8.2 centimeters. What is the perimeter?
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)
Five times the length of one of the sides.
add all the sides ???
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
A nonagon has nine sides.
