Question

Pinky runs around a square field of side 100m.Bob runs around a rectangular field with length 150m and breadth 100m.Who covers more distance and by how much?

Answer 1

Answer:

perimeter of squares =4×side

pinky=4×100=

400

perimeter of rectangle =2(l+b)

2(150+100)

2×250=500

:500-400=100

hence Bob covered more distance by 100m
