Question

Each side of a regular polygon is 2.5 cm in length. The perimeter of the polygon is 12.5cm. which type of polygon this is?​

Answer 1

one side is 2.5 and perimeter is 12.5

for total no of sides we devide perimeter by side as it is regular polygon

so it comes as 12.5/2.5= 5

hence it has 5 sides so it's pentagon.

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.
