Question

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

Answer 1

sweety = find the perimeter of the square park = 75 ×4 =300 m

bulbul =find the perimeter of the rectangular park =2(l+b) =2(60+45) =2×105 =210

bulbul covers less distance than sweety

Answer 2

Answer :

Given that,

Side of square park = 75 m

And,

Length of rectangular park, l = 60 m

Breadth of rectangular park, b = 45 m

Therefore,

Distance covered by Sweety = Perimeter of square park

We know that,

Perimeter of square park = 4 × Side

= 4 × 75 =300 m

Also,

Distance covered by Bulbul = Perimeter of rectangular park

We know that,

Perimeter of rectangular park = 2 × (l + b)

= 2 × (60 + 45) = 2 × 105

= 210 m

Therefore, Bulbul covers less distance as compared to Sweety.

Hope it helps !!!
