Question

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

Answer 1

Finding the length of side of a regular decagon :

Number of sides of a regular decagon $=10$

According to the question,

Length of piece of wire will be equal to the perimeter of the decagon.

Therefore,

Perimeter of a regular decagon $=10\times side$

$750=10\times side$

$side=\frac{750}{10}$

$side=75cm$

Hence , the length of side of a regular decagon is $75cm$
