Question

Each side of a regular polygon is 3.5 cm in length. The perimeter of the polygon is 21 cm. How many side does the polygon have​

Answer 1

Answer:

Step-by-step explanation:

length of each sides of  polygon is 3.5cm

perimeter of polygon is 17.5 cm

Therefore ,

No of sides the polygon has = perimeter/length

                                               = 17.5/3.5

                                                =5 sides

hence , the polygon is a Pentagon [5 sides]

Answer 2

Answer: we know the polygon have each side measure 3.5 cm

and we know the perimeter i.e. 21 cm

so let sides of perimeter be Y

21=Yx3.5

Y=21/3.5

Y=6
