Answer 2

Step-by-step explanation:

perimeter of rectangular field =2(length + breadth)

2(72+58) = 2 *130 =260m

distance covered in taking 2 round of field = 2*260 = 520 m =520/1000=52/100

amar walks at rate of 3 km / hr

to cover 3 km it takes 1 hour

to cover 1 km it will take 1/3 hr

to cover 52/100 km it will take 52/100 *1/3

=52/300 hour=52/300 *60 min=52/5 min =10.4minutes
