Answer:
14.14m
Explanation:
Given side of square =10m, thus perimeter P=40m
Time taken to cover the boundary of 40 m =40 s
Thus in 1 second, the farmer covers a distance of 1 m
Now distance covered by the farmer in 2 min 20 seconds = 1×140=140m
Now the total number of rotation the farmer makes to cover a distance of 140 meters =totaldistance/Perimeter
=3.5
At this point, the farmer is at a point say B from the origin O
Thus the displacement s=√( 10)2+(10)2
from Pythagoras theorem.
s=10√2
=14.14m
