If a person has two rectangular fields. The larger field has thrice the length and 4 times the width of the smaller field. If the smaller field has a length 50% more than the width.If a person takes 20 minutes to complete one round of a smaller field then what is the time required to complete one round of a larger field ?

• Answer is: 68 minutes
  Let the width of the smaller rectangle is 4 units
  then, the length of the smaller rectangle is 6 units(that is 50% more than the width)
  Now the perimeter of the rectangle is 2(6+4)=20units
  So, 20 units is covered in 20 units, implies covers one unit in one minute
  So Now coming to the larger rectangle
  The Width =16Units, Length =18units, perimeter=2(16+18)68 units
  Thus, to cover the larger field, 68 minutes required to cover the rectangle.
