Answer 2

To find : length of side of regular pentagon .

Given :  perimeter of regular Pentagon is $28.5$ cm .

Solution :

• As per given data we know that ,perimeter of regular Pentagon is $28.5$ cm .
• We know that all the sides of regular pentagon are equal .
• If ' $a$ ' is the side of regular pentagon then perimeter is given by ,

• Perimeter of regular pentagon = $5a$

       $28 . 5 =5a \\ a = \frac{28.5}{5} \\a = 5.7\ cm$

Hence , length of each side of regular pentagon is $5.7 \ cm$ .
