Question

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

Answer 1

Answer:

5 sides

Step-by-step explanation:

in a regular polygon all sides are equal

therefore the perimeter is

p = (no.of sides) x (length of each side)

12.5 = (no.of sides) x 2.5

(no.of sides) = 12.5/2.5 = 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.
