Anisha walks around a square park of side 90 m. Vandana walks around a rectangular park of length 80 m and breadth 60 m. Each one makes four rounds. Who covers less distance and by how much?

Anisha walks around 1440m

Vandana walks 1120m

Vandand walks less by 330m

Vandana covers less distance by 320 meters

Step-by-step explanation:

Let's calculate the perimeter of both parks.

Square park:

P = 4s

P = 4 (90)

P = 360 m

D = 360 * 4 (rounds) = 1440 m

Rectangle park:

P = 2 (l + w)

P = 2 (80 + 60)

P = 2 (140)

P = 280 m

D = 280 * 4 (rounds) = 1120 m

As you can see,

Anisha walked a distance of 1440 m.

Vandana walked a distance of 1120 m.

1440 - 1120 = 320 m

From this info, Vandana covers less distance than Anisha by 320 m.
