Length of the rectangle =130m
Breadth of the rectangle =110m
∴ perimeter of the rectangle =2(1+b)
=2(130+110)
=2(240)
=480m
Now, the total distance covered =1440m
If he covers 480m in one round,
Total number of rounds he will cover
=totaldistance/perimeter
=1440/480
=3 rounds
∴ Thus, he will cover the distance in three rounds.
