Question

Each side of a regular polygon is
8.1 cm long. the perimeter of the polygon is 72.9cm. find the number
of sides of the polygon. ​

Answer 1

Answer:

Given Regular Polygon has 9 side

Step-by-step explanation:

Regular polygon is a polygon that has all sides of same length as well as all angles of same measures.

\textbf{We are given following values,}We are given following values,

Length of each side = 8.1 cm

Perimeter of the polygon = 72.9 cm

\textbf{We know that in a regular polygon,}We know that in a regular polygon,

Perimeter = (Number of sides) × (Length of each side)

=> 72.9 = (Number of sides) × 8.1

=> Number of sides = 72.9/8.1

=> Number of sides = 9

\textbf{Given Regular Polygon has 9 sides.}Given Regular Polygon has 9 sides.

Answer 2

Step-by-step explanation:

Side of the regular polygon = 8.1cm

No.of sides = ?

Perimeter = 72.9 cm

solution:

perimeter = X × S units

72.9 cm = X × 8.1 cm

X = 72.9cm ÷ 8.1cm

X = 9

◇ The no.of sides is 9
