Sweety runs around a square park of side 75 m. Bulbul runs around a rectangular park with length 60 m and breadth 45 m. Who covers less distance?

Answer:

Now, distance covered by in one round = Perimeter of park \[\therefore \]Perimeter of square park \[=4\times \]Length of a side \[=4\times 75m=300m\]and distance covered by Bulbul in one round = Perimeter of rectangle \[=2\times \] (Length + Breadth) \[=2\times (60+45)m=2\times 105m=210m\] Since, \[300\text{ }m>210m\] Hence, Bulbul covers less distance.
