the distance covered by the boy in one round = 252 m

Step-by-step explanation:

boy runs along edges

the distance covered by the boy in one round. = 60 + (1/2)2 * π * 21  + 60 +  (1/2)2 * π * 21

= 120 + 2 * π * 21

π = 22/7

= 120 + 2(22/7)21

= 120 + 44 * 3

= 120 + 132

= 252 m

the distance covered by the boy in one round = 252 m
