Question

If each side of a regular polygon is 7.32cm and its perimeter is 109.80cm then find the numbers of sides of the polygon.

Answer 1

Answer:

109.80cm

7.32cm. is 15 sides

Answer 2

Question :-

Each side of a regular polygon is 7.32 cm and its perimeter is 109.80 cm. Find the number of sides of the polygon.

____________________

Solution :-

➲ Given Information :-

• Measure of each side of polygon ➢ 7.32 cm
• Perimeter of the polygon ➢ 109.80 cm

➲ 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,

⇒ $\sf {number \: of \: sides \: of \: polygon = \dfrac{109.80 cm}{7.32 cm} }$

Cancelling & Calculating further, We get,

⇒ $\sf{number \: of \: sides \: of \: polygon = \red{ 15}}$

∴ Number of sides of the polygon = 15

___________________

Final Answer :-

• The number of sides of this polygon is 15. This means that this figure is a Regular Pentadecagon.
