Question

each side of a polygon is 2.9 cm in length and its perimeter is 17.4 cm. how many sides does the polygon have?

full solution marking as brainilist please????​

Answer 1

Answer:

Number of sides in the polygon = 6

Step-by-step explanation:

given that,

each side of a polygon is 2.9 cm

given

perimeter of the polygon = sum of sides of the polygon

and

if there is a regular polygon

then perimeter of the polygon

= length of side × number of sides

let the number of sides be x

then,

According to the question,

2.9x = 17.4

x = 17.4/2.9

x = 6

so,

Number of sides in the polygon = 6

so,

this polygon is

Hexagon

Answer 2

Answer:

Number of sides in the polygon = 6

Step-by-step explanation:

given the

length of each side of a polygon = 2.9 cm

so,

this is regular polygon

given perimeter = 17.4 cm

and we know that

perimeter of a regular polygon = length of side × n

where,

n is the number of sides

so,

2.9n = 17.4

n = 17.4/2.9

n = 6

so,

Number of sides in the polygon = 6
