Detailed Solution

Given that a field is of length 110 m and width 80 m.
Distance covered by the farmer = perimeter of the field
Since the field is rectangular, so,
Distance covered = 2×(length+breadth)
Distance covered = 2×(110+80)
Distance covered = 2×190
Distance covered = 380 m 
So, the farmer will cover 380 m.
Hence, the correct option is 3.
