Question

side of a regular polygon is 3.5 cm in length. The perimeter of the polygon is 17.5 cm. How many sides does the polygon have?

Answer 1

perimeter=sides×side's length
so,as given p=17.5
& l=3.5
so no.of sides=
$\frac{17.5}{3.5}$
=5

Answer 2

Answer:

5

Step-by-step explanation:

A regular polygon means that all the sides of the polygon will have the same lengths.

Now, one side of the polygon is equal to 3.5 cm.

Let the polygon has n number of sides.

Hence, the perimeter of the regular polygon will be given by 3.5n cm.

Given that the polygon perimeter equals to 17.5 cm.

Therefore, the number of sides of the polygon will be given by,

3.5n=17.5, ⇒ n =17.5/3.5= 5.(Answer)
