Question

A piece of wire is $750cm$ long . What will be length of each side if the wire is used to form a regular pentagon.

Answer 1

Finding the length of side of a regular pentagon :

Number of sides of regular pentagon $=5$

According to the question,

Length of the wire will be equal to perimeter of the regular pentagon.

Therefore,

Perimeter of regular pentagon $=5\times side$

$$\begin{gathered} 750=5\times side \\ side=\frac{750}{5} \\ side=150cm \end{gathered}$$

Hence, length of each side of regular pentagon is $150cm$
