perimiter=measure around the field or width+width+legnth+legnth or 2width+2legnth
p=perimiter
w=width
l=legnth
p=2w+2l
p=1.48 km
1km=1000m
1.48km=1480 m
p=1480
1480=2w+2l
l=460
subsitute
1480=2w+2(460)
1480=2w+920
subtract 920 from both sides
560=2w
divide both isdes by 2
280=w
width=280 meters

280 meters wide
because if you double 460 and subtract the answer from 1480 then divid by 2 you get the answer.
