The length and breadth of a rectangular field are 50 m and 40 m respectively. Find the distance travelled by a boy in walking along the boundary in

i. one complete round ii. 5 complete rounds

180M (1 round); 900M (5 rounds)

Step-by-step explanation:

Solve for perimeter with is 2L + 2 W.

1. 2 (50) + 2 (40) =

2. 100 + 80 = 180

He walked 180M for 1 complete round. To determine 5 complete rounds, multiply by 5.

180X5 = 900 M
