Question

Pinky runs around a square field of side 7500 cm, Bob runs around a rectangular field with length 160 m and breadth 150 m. Who covers more distance and by how much ?

Answer 1

Answer:  Bob runs more and covers more distance than Pinky by 54500 cm.

Explanation:

Since we have given that

Length of rectangle = 160 m

Breadth of a rectangle = 150 m

Perimeter of a rectangle is given by

$2(Length+breadth )\\=2(160+150)\\=2\times 310\\=620\text{ m}$

Now, we need to change it into cm ,

As we know that

$1\text{ m}=100\text{ cm}\\620\text{ m}=62000\text{ cm}$

So, we can see that

Bob runs more and covers more distance than Pinky by

$62000-7500=54500\text{ cm}$.
