Answer:

perimeter = 29.25

=> 3.25 × X = 29.25 ( X is no. of sides )

=> X = 29.25/3.25

=> X = 2925/325

=> X = 585/65

= 117/13

= 9

( that is nanogon means it has 9 sides )

Question :-

Each side of a regular polygon is 3.25m 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.
