Each side of a rectangular regular polygon is 2.5 cm in length.The perimeter of the polygon is 12.5 cm. How many sides does the polygon have?
Each side of the polygon = 2.5 cm
Perimeter of the polygon = 12.5 cm
Let the number of sides of the polygon = n
We also know that perimeter of a polygon = n length of each side
Therefore, putting he value of perimeter in above equation , we get
Hence, number of sides of the given polygon is 5.
