Answer:
Length of rectangular field=240m
Breadth of the rectangular field=160m
Perimeter of the rectangular field=2(240+160)
=2(400)
=800m
Length of the rope for 1 round=800m
Thus, length of the rope for 5 rounds=5x800
=4000m
Cost of rope per meter=Rs 100
Cost of the rope for 4000m=100x 4000=Rs4,00,000
