He walks around a square park
Side of square park = 90 m
Perimeter of square = One round of the field by Aryan
Perimeter = 4 x side = 4 x 90 = 360 m
In four rounds = 360 x 4 = 1440 m
-------------------------------------------------------------------------------------------------------
Ananya's Case ----
Perimeter of rectangular field = 1 round by ananya
Perimeter = 2( l + b) = 2( 90 + 60) = 2 x 150 = 300m
In 4 rounds = 4 x 300 = 1200 m
1440m > 1200m
So, Ananya covered less distance by 1440 - 1200 = 240 m
