YARDGARD309312A Cage Wire Fencing, Height-24 Inches x Length-25 Ft, Color - Galvanized

It is described as 1 inch by 1 inch, however the pictures shows it differently. It seems to be pictured as 1 x 2. Which is is?

I want to put this on the outside of a cage. Do I need any wire, or bolt cutters to assemble this?

Does this have spokes at the bottom where you can put in the ground?

is this fencing rust proof or does it need to be treated to prevent rust
