Solution:Concept- We must first comprehend the definition of a polygon in order to calculate the regular six-sided polygon's perimeter. Utilizing the perimeter formula and the side length specified in the question, compute it.
Side length = 6.5 cm
Any polygon's perimeter is equal to the sum of the dimensions of all its sides. Every side of a regular polygon is the same length. In the case of a normal six-sided polygon, the perimeter is equal to the total of the six equal sides. A typical six-sided polygon looks like this:
The polygon's perimeter is .
where "a" denotes the polygon's side length.
The polygon's given side is 6.5 cm long. Consequently, a = 6.5 cm
Circumference = 6 + 6.5 cm= 39cm
39 cm is the perimeter.
Hence, the correct answer is option 1.
