Distance covered by Sweety = Perimeter of square park 

Perimeter of square = 4 x side 

= 4 x 75 = 300 m 

Thus, distance covered by Sweety is 300 m. 

Now, distance covered by Bulbul = Perimeter of rectangular park 

Perimeter of rectangular park = 2 x (length + breadth) 

= 2 x (60 + 45) 

= 2 x 105 

= 210 m 

Thus, Bulbul covers the distance of 210 m. 

And Bulbul covers less distance.
