Question

Rahim and peter go for a morning walk, Rahim walks around a square path of side 50 m and Peter walks around a rectangular path with length 40 m and breadth 30 m. If both of them walk 2 rounds each, who covers more distance and by how much?

Answer 1

Distance covered by Rahim

= 50 × 4 m

= 200 m

If he walks 2 rounds, distance covered = 2 × 200 m
= 400 m

Distance covered by peter

= 2 (40 + 30) m

= 2(70)m

= 140 m

If he walks 2 rounds, distance covered = 2 × 140 m
= 280 m

∴ Rahim covers more distance by (400 – 280) = 120 m
