The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is the length of the plot in metres?

A. 40 B. 50
C. 120 D. Data inadequate
E. None of these

• Option E None of these
  
  Let the breadth is x
  and length=20+x
  Perimeter=5300/26.50=200
  x+20+x=200
  2x=180
  x=90
  length =20+90=110

• Option E NONE OF THESE
  
  Let the breadth is x
  and length=20+x
  Perimeter=5300/26.50=200
  2(x+20+x)=200
  2x+20=100
  x=40
  length =20+40=60

• perimeter formula is2(l+b)
  2(x+x+20)=200
  4x+40=200
  4x=160

• option e
  
  breadth=x
  length=x+20
  perimeter=5300/26.50=200
  perimeter=2(length+breadth)
  2(x+20+x)=200
  4x+40=200
  x=160/4
  x=40
  
  length=40+20=60
