Question

the side of a regular polygon is 2.5cm. if perimeter of the polygon is 15cm, then find the number of sides of the polygon

Answer 1

side of a regular polygon = 2.5cm

perimeter of regular polygon= 15cm

no. of sides of regular polygon= perimeter/length of one side

=15/2.5

=6

Answer 2

Side = 2.5 cm

perimeter= 15 cm

perimeter of polygon= n x s

n = no. of sides

s = measure of one side

n x 2.5 = 15

15÷2.5 = n

n = 6
