Answer 2

Answer:

Given :-

• The perimeter of a regular pentagon is 100 m.

To Find :-

• What is the each side of a regular pentagon.

Formula Used :-

$\sf\boxed{\bold{\pink{Perimeter\: of\: Pentagon =\: 5(Side)}}}$

Solution :-

Given :

• Perimeter = 100 m

According to the question by using the formula we get,

↦ $\sf 5(Side) =\: 100$

↦ $\sf 5 \times Side =\: 100$

↦ $\sf Side =\: \dfrac{\cancel{100}}{\cancel{5}}$

➠ $\sf\bold{\red{Side =\: 20\: m}}$

$\therefore$ The each side of regular pentagon is 20 m.
