Question

Each side of a regular polygon is 5.2m and its perimeter is 36.4m . Find the number of sides of the polygon

Answer 1

perimeter= length of the all side present in the polygon
suppose l no. of sides present in the polygon , then
l × 5.2 = perimeter
l = 36.4/5.2 =7
7 sides are present in the polygon.

Answer 2

Answer:

The number of sides of polygon is 7

Step-by-step explanation:

Regular Polygon : A polygon is regular when all angles are equal and all sides are equal.

Perimeter = 36.4 m

Length of each side = 5.2 m

Let number of sides in the polygon be n

Now, Perimeter = Sum of all sides of polygon

⇒ Perimeter = n × 5.2

⇒ 36.4 = n × 5.2

⇒ n = 7

Hence, the number of sides of polygon is 7 and the polygon is regular heptagon
