Question

each side of regular side of polygon is 3.25 cm its perimeter is 29.25 find the number of sides of polygon​

Answer 1

Answer:

Let number of sides be x

Perimeter = sum of all sides

29.25 = 3.25x

X = 29.25/3.25

X= 9

Number of sides is 9

Question :-

Each side of a regular polygon is 3.25 cm and its perimeter is 29.25 cm. Find the number of sides of the polygon.

____________________

Solution :-

➲ Given Information :-

• Measure of each side of polygon ➢ 3.25 cm
• Perimeter of the polygon ➢ 29.25 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,

⇒ $\sf {number \: of \: sides \: of \: polygon = \dfrac{29.25 cm}{3.25 cm} }$

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 Enneagon/Nonagon.
