Question

Each side of a 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:

Number of sides of given polygon = 5

Number of sides of given polygon = 5(Pentagon)

Step-by-step explanation:

Let each side of a polygon be 's'.

s = 2.5 cm ( given )

Perimeter of the polygon (P) = 12.5 cm

Let number of sides of the polygon = n

$n = \frac{P}{s}\\=\frac{12.5}{2.5}\\=5$

Therefore,

Number of sides of given polygon = n = 5

Answer 2

Answer:

Let each side of a polygon be 'x'.

= 2.5x = 12.5

= x = 12.5 = 125 X 10  = 1250 = 125/25 = 5

          2.5      25 X 10       250      25 /25    

Therefore, The polygon has 5 sides.
