Given :

• Perimeter of a regular pentagon is 100 cm.

To Find :

• How long Each side ?

Solution :

• We know that,

• Pentagon have 5 side

So,

${ \pink{ \boxed{ \sf{5a \: = 100}}}}$

• Now, Substitute the values :-

${ \sf{5a = 100}}$

${ \sf{a = \frac{100}{5} }}$

${ \boxed{ \sf{a = 20 \:cm}}}$

• Hence, Side of Pentagon is 20 cm.

${ \red {\mathtt{Verification :}}}$

We have

• Perimeter of Pentagon is 100 cm
