Step-by-step explanation: Length = 300m
Breadth = 200m
Perimeter of rectangular park = 2 (l+b)
= 2 (300+200)m
= 2(500)m
= 1000m or 1 km.
Karan takes 4 round.
So distance covered by Karan = 4 × Perimeter
= 4 (1)
= 4 km
So he covered 4 km.
Number of round required to cover 9km = 9/Perimeter
= 9/1
= 9 rounds
So he should take 9 rounds to cover the distance of 9km
