l = 80m
b= 35 m
perimeter of the playground = l*b
= 80* 35
= 2800m
if the boy covers 1.5 m/ s in one round , then he covers 2,800m in 1866.66m/s ( 2800/1.5= 1,866.67)
b= 35 m
perimeter of the playground = l*b
= 80* 35
= 2800m
if the boy covers 1.5 m/ s in one round , then he covers 2,800m in 1866.66m/s ( 2800/1.5= 1,866.67)
