Dear Student
Given, length of rectangular field = 90 m

and breadth = 70 m.

Distance covered by man in completing 1 round along the rectangular field = perimeter of rectangular field

= 2(l + b) = 2 (90 m + 70 m) = 320 m

∴ distance covered by the man in completing 5 rounds = 5 × 320 m = 1600 m = 1.6 km

Also, speed with which man walks = 4 km/hr

Time taken by man in completing 5 rounds = Distance/speed

= 1.6/4

= 0.4 hour

= 0.4 × 60 minutes = 24 minutes
