A field has a pere a field has a perimeter of 1.48 kilometres it is 460 metres long how wide is the field

280 meters wide

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

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
