Question

The length of each side of a regular polygon is 1.3 cm. The perimeter of polygon is 10.4 cm. How many side does the polygon have? ​

Answer 1

Answer:

taking no of sides as x

1.3x=10.4

x=10.4/1.3

x=104/13

x=8

Step-by-step explanation:

Answer 2

Given:

The length of each side of a regular polygon is 1.3 cm.

To find:

Number of sides in the polygon.

Solution:

1) The perimeter of the polygon is 10.4 cm.

The length of the side is 1.3 cm

2) In the regular polygon:

• $Number~of~Sides=\frac{Perimeter}{length~of~side}$
• $N = \frac{10.4}{1.3}$
• N = 8

So the regular polygon has 8 sides which is called octagon.
