Step-by-step explanation:
Dimensions of a rectangular field= 72cm by 58cm
perimeter of the rectangular field= 2( l+b )
=2×( 72+58)
= 2×130
= 260cm
∴ Distance taken by Amar in taking two rounds= 2×260m
= 520m
Speed of Amar= 3km/hr
=3×1000/3000 m/sec
= 5/6 m/sec
Total time taken by Amar to cover the distance= Distance/speed
= 520/5/6 = 520×5/6
= 104×6
= 104×6/60 min.
= 10.4 min.
