Question

Each side of a regular polygon is 2.5 cm in length. The perimeter of the polygon is 12.5cm. How many sides does the polygon have?

Answer 1

Answer:

The polygon have = 5 sides.

Step-by-step explanation:

let the number of sides of a regular polygon = n

given :

    length of each side = 2.5 cm

    perimeter of the polygon = 12.5 cm

according to formula

number of sides of polygon $\times$ length of each side = perimeter of the polygon

⇒ n$\times$2.5 = 12.5

⇒ n = $\frac{12.5}{2.5}$

⇒ n = 5

Answer 2

solution:

the perimeter of a regular polygon is a sum of the length of all its equal sides= 12.5cm.

length of each side=2.5cm.

thus, the number of sides =12.5= 125 =5

2.5 25

the polygon has 5 sides.
