Answer» The farmer has to cover THREE times the perimeter of that field. Therefore, Total length of ROPE REQUIRED is thrice its perimeter. Perimeter of the field = 2 × (length + BREADTH) Perimeter of the field = 2 × (240 m + 180 m) Perimeter of the field = 2 × 420 m Perimeter of the field = 840 m ____________________ Total length of rope required = 3 × 840 m Total length of rope required = 2520 m |
