Question

A side of a regular polygon is 3.5 cm in length the perimeter of the polygon is 17.5 ​

Answer 1

Answer:

Number of Sides in the given polygon=5

Explanation:

Given that:-

Side of the regular polygon =3.5cm

Length of the perimeter of the regular polygon = 17.5cm

Perimeter of a regular polygon=sum of all sides

let the number of sides be "n" then

perimeter=n×length of the side

=>n×3.5=17.5

=>n=17.5/3.5

=>n=(175/10)/(35/10)

Cancelling 10

=>n=175/35

=>n=5

Number of Sides in the given polygon=5

So ,it is a pentagon
