Well, if it's a square background, then the length of two sides must be the same. So we can square root 256 to get the length of one side.  You can plug that into a calculator, but it's easy to memorize that it is 16.

 

 

I don't really know what you want to know...but here are some possible answers: 

Length of one side: 16 meters

The total length of fence needed: 64 meters

 

Correct me if I'm wrong. (Getting a lot of questions wrong these days...laugh)
