Question 1135466

The perimeter of a regular octagon is equal to {{{50cm}}}. 

Find the length of its side.

 A regular octagon is a closed figure with {{{8}}} sides of the same length.

if the length of the side is {{{a}}}, then

{{{P=8a}}}

since given {{{P= 50cm}}}, we have

 {{{8a=50cm}}}

{{{a=50cm/8}}}

{{{a=6.25cm}}}
