Alright, lets get started.
A regular decagon has 10 equal sides.
The perimeter of a regular decagon will be = 10 a
where a is the length of the side
So,
[tex] 10 a = 350 [/tex]
Dividing both sides with 10
[tex] \frac{10 a}{10} = \frac{350}{10} [/tex]
a = 35 feet
Hence the length of the side is 35 feet. : Answer
Hope it will help :)
