Question

The length of a rectangular field is 8meters less than twice its breadth. If the perimeter of a rectangular field is 56 meters, find its length and breadth ?

Answer 1

let the breadth be x
therefore. length=2x-8
  the total perimeter=2(l+b)=56
                               ⇒l+b=28
                               ⇒x+2x-8=28
                              ⇒3x=36
                              ⇒x=12
so the breadth is 12 m and length is 16m.
