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?

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.

Anisha walks around 1440m

Vandana walks 1120m

Vandand walks less by 330m
