1‌km=1000m
The area of the square =0.01km2
(‌ Side ‌)2=0.01km2
⇒(‌ Side ‌)2=0.01×1000×1000=10000m2
⇒‌ Side ‌=100m
Perimeter of square =4× SIde
⇒ Perimeter of square =4×100=400m
1m=100‌cm
⇒150‌cm=1.5m
Perimeter of rectangle =2×( Length + Breadth )
⇒ Perimeter of rectangle =2×(1.5+100)
⇒ Perimeter of rectangle =203m
Distance covered in 1 round =203m
⇒ Distance covered in 10 rounds =203×10=2030m
He has to do 2030÷400=5.075
∴ Approx 5 rounds he has to do cover the same number of round.
