Question

Khushi ran 2 times around a square park whose each side was equal to 90 m. How much distance did she cover in total?
​

Answer 1

Step-by-step explanation:

square park 90 m

P- 4×90

P- 360m

360m×2

so 720 m

Answer 2

Answer:

This is an interesting question. Here is the solution:-

Total distance to be covered - 9km

1km=1000m

9km=9×1000 = 9000m

First we will look upon Kanchan's status:-

Length of side of square=90m

Perimeter=4×side

4×90=360m

So, 360m is the perimeter of the square.

Now, total distance to be covered=9000m

Total rounds Kanchan requires to complete 9000m= 9000÷360=25

So, kanchan needs to take 25 rounds to cover the distance of 9000m.

Now, let us look at the status of Vinita:-

Dimensions of rectangular park = 300m×200m

Perimeter = 2×(length + breadth)

2(300+200)

2×500

1000m

Rounds required to cover 9000m = 9000÷1000=9

So, Vinita needs to cover 9 rounds in order to complete the distance of 9000m. I hope it helped you.
