Answer:
The perimeter of the regular nonagon is 111.6 cm
Step-by-step explanation:
In this question, we are asked to calculate the perimeter of a regular nonagon given the apothem and the length of its side
Since the polygon is regular, it means the length of its sides are equal.
The polygon we are dealing with here is a nonagon meaning it is a 9 sided polygon
Mathematically, the perimeter is ;
P =n * s
where n is the number of sides and a is the length of one of the side of the polygon
From the question, our s = 12.4 cm
Plugging this into the perimeter equation, we have;
P = 12.4 * 9 = 111.6 cm
