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:

The distance each girl covers in one round is the same as the perimeter of the respective fields. Therefore, the distance that Sweety covers in one round = Perimeter of a square park \[=4\times side\] \[=4\times 75\text{ }m\] \[=300\text{ }m.\] Also, the distance that Bulbul covers in one round = Perimeter of a rectangular park \[=2\times (length+breadth)\] \[=2\times (60\text{ }m+45\text{ }m)\] \[=2\times 105\text{ }m\] \[=210\text{ }m\] Since \[210<300\], so Bulbul cover less distance than Sweety
