Answer:
100 m
Explanation:
Suppose the farmer start from point A, after completion of one round he will reach A point again. In completion of one round he take 15min and there are 3 sides of triangle and this is a equilateral triangle , so he will take 5 min to cover one side of triangle .
15/3 = 5
So, in 10 min he will cover two sides and reach point B.
Displacement between A and B is the exact distance between them i.e. 100m .
So in 10min he’ll displace 100m
