x is the width of the field. x+80 is the length. Your formula is therefore x+x+x+80+x+80 (or 4x+160)=1080.
4x+160=1080.
4x=920
divide 920 by 4 and you have your width. Add 80 to that and you have your width.
Good luck!

Perimeter = 2length + 2width.
1080 = 2(width+80) +2width
1080 = 2width + 160 + 2width = 4width + 160
920 = 4width
230 = width
length = 230 + 80 = 310

The length would be 310 ft and the width would be 230 ft.
