The perimeter of a nonagon is the sum of its side lengths

The perimeter of the regular nonagon is 840.7 units

How to determine the perimeter

The in-radius of the regular nonagon is given as:

r =17

The perimeter is then calculated as:

[tex]P = \frac{18r}{\tan(pi/9)}[/tex]

Substitute 17 for r

[tex]P = \frac{18 * 17}{\tan(pi/9)}[/tex]

Evaluate the product of 18 and 17

[tex]P = \frac{306}{\tan(pi/9)}[/tex]

Evaluate the quotient

[tex]P =840.7[/tex]

Hence, the perimeter of the regular nonagon is 840.7 units
