》To find :

Who covered more distance and by how much ?

》Given :

Pinky runs around square field of side 75 m.

Bob runs around rectangular field of length 160 m and breadth 105 m.

》Solution :

In order to find who covered more distance and by how much, we need to find the perimeter of both the fields and then subtract the less one from greater one.

Now,

Distance covered by Pinky -

Perimeter =  

Perimeter =  

Perimeter =  

So, Pinky covered 300 m.

Also,

Distance covered by Bob -

Perimeter =  

Perimeter =  

Perimeter =  

So, Bob covered 530 m.

Now, it is clear that Bob covered more distance than Pinky.

》

Therefore, Bob covered 230 m more than Pinky.
