Answer 1

the number of sides are 9

1. 5.13/5.7=9

Answer 2

Question :-

Each side of a regular polygon is 5.7 m and its perimeter is 51.3 m. Find the number of sides of the polygon.

____________________

Solution :-

➲ Given Information :-

• Measure of each side of polygon ➢ 5.7 m
• Perimeter of the polygon ➢ 51.3 m

➲ To Find :-

• Number of sides of the polygon

➲ Concept :-

• Area And Perimeter of Plane Figures

➲ Explanation :-

• In order to find the number of sides of the polygon, We have to divide the ' perimeter of the polygon ' with the ' measure of each side of polygon '. The resulting values will be the total number of sides present in the polygon.

➲ Formula Used :-

• $\underline{ \underline{ \boxed{ \boxed{ \bf \red{number \: of \: sides \: of \: polygon = \dfrac{perimeter \: of \: polygon}{measure \: of \: each \: side \: of \: polygon} }}}}}$

➲ Calculation :-

Simply, substituting the values in the formula, We get,

⇒ $\sf {number \: of \: sides \: of \: polygon = \dfrac{perimeter \: of \: polygon}{measure \: of \: each \: side \: of \: polygon} }$

Substituting the values given, We get,

⇒ $\sf {number \: of \: sides \: of \: polygon = \dfrac{51.3 m}{5.7 m} }$

Cancelling & Calculating further, We get,

⇒ $\sf{number \: of \: sides \: of \: polygon = \red 9}$

∴ Number of sides of the polygon = 9

___________________

Final Answer :-

• The number of sides of this polygon is 9. This means that this figure is a Regular Nonagon.
