Question

The length of a wire is $72m$. Find the length of each side if the wire is used to form a regular pentagon.

Answer 1

Length of each side a regular pentagon

Given, length of a wire to form a regular pentagon$=$ $72m$

$\therefore$ Perimeter of a regular pentagon$=$ $72m$

$\begin{array}{rcl}5\times side& =& 72m\\ side& =& \frac{72}{5}m\\ side& =& 14.4m\end{array}$

Therefore,length of each side a regular pentagon is $14.4m$.
