The length of a rectangular field is 7/5 its width. If the perimeter of the field is 240 meters, what are the length and width of the field?

• let length=l width=w
  so, l=(7/5)w
  and 2(l+w)=240
  => l+w=120
  => (7/5)w+w=120
  => 12w/5=120
  => w=50
  and l=(7/5)*50=70
  So, length=70 and width=50

• let x be the width length 7/5x, then 2(x+7/5x)=240 by solving eq we get x=100 and length 7/5x = 140
