Question

Sachin takes 10 rounds of a rectangular park, 50 m long and 20 m wide. Find
the total distance covered by him.​

Answer 1

Answer:

1 km and 400 meter.

Step-by-step explanation:

given length - 50 m

wide- 20 m

so, perimeter - 2(l+b)

2(50+20)

2*70

140 meter for one round

since he has taken 10 round so, total distance covered by him is 10 *140 meter

i.e, 1400 meter

equal to 1 km & 400 meter.

Answer 2

Given:

Sachin walks 10 rounds on a rectangular field of length 50 meters and breadth of 20 meters.

To Find:

The distance walked by Sachin after 10 rounds.

Solution:

1. The total distance covered by Sachin for 1 round will be equal to the perimeter of the rectangle.

2. Hence, the total distance covered by Sachin for 10 rounds will be,

=> Total distance covered by Sachin for 10 rounds = 10 x perimeter of the rectangle.

3. Perimeter of the rectangle is calculated using the formula,

=> Perimeter of a rectangle = 2 x ( length + breadth ),

4. Substitute the values of length and breadth in the above formula,

=> Perimeter of the rectangle = 2 x ( 50 + 20 ),

=> Perimeter of the rectangle = 2 x 70,

=> Perimeter of the rectangle = 140 meters.

5. Hence, the distance covered by Sachin per round is 140 meters,

=> Total distance covered by Sachin after 10 rounds = 140 x 10 = 1400 meters.

Therefore, the total distance covered by Sachin after 10 rounds is 1400 meters.
