Question

Amit runs around a rectangular Park which is 120 M long and 80 m wide find the distance he covers in 3 rounds​

Answer 1

Perimeter of a rectangle

= 2 × (l + b)

= 2 × (120 + 80)

= 2 × 200

= 400m.

The distance for 3 rounds

= 400 × 3

= 1200m

Hence, the distance covered by amit is 1200m = 1.2km.

Hope it helps you.

Mark me as the brainliest please.

Answer 2

Length of the rectangular park = 120m.

Breadth of the rectangular park =80m.

So,the perimeter of the park= the perimeter of a rectangle=2(l + b)

= 2(120 +80)= 400m

No of rounds Arjun had taken =3 rounds.

Total distance covered by Arjun in 3 rounds = 400 ×3= 1200m.(ans)
