Step-by-step explanation:

Length of each side of the polygon = 2.5 cm

Perimeter of the polygon = 12.5 cm

Let the number of sides of the polygon be z.

2.5 z = 12.5 ( Perimeter = Length of one side multiplied by the number of sides)

or, z =

Thus, the polygon has 5 sides.

Answer 2

$\huge\tt\red{Answer}$

Let the number sides a regular polygon = x

Perimeter of giver regular polygon =12.5cm

Length of each side =2.5cm

2.5x=12.5

$x=\frac{12.5}{2.5}$

x=5

No. of sides a regular polygon have=5 sides.
