Sweety runs around a square park of side 75 m. Bulbul runs around a rectangular park with a length of 60 m and breadth 45 m. Who covers less distance?
Distance covered by Bulbul = Perimeter of the rectangular park.
Distance covered by Bulbul = 2×(length + breadth).
= 2×(60 + 45).
= 2×105 = 210 m.
Distance covered by Sweety = Perimeter of the square park.
Distance covered by Sweety = 4×side length
= 4×75 = 300 m.
Since 210 m < 300 m.
Therefore, Bulbul covered lesser distance.
