Problema Solution
The Canadian Football League requires that rectangular playing fields have specific dimensions. If the perimeter of the field is 350 yards and the length is 20 yards less than twice the width, find the dimensions of the playing fields.
Answer provided by our tutors
let width be x
so length will be 2x-20
so perimeter=2*(x+2x-20)=350
=>6x-40=350
=>6x=390
=>x=65
=>width=65
so length 2*65-20=110
