Solution

## The correct option is B 600 mGiven: Length of the park, l=120 m Breadth of the park, b=80 m Number of laps around the park, n=3 Perimeter of the park, P=2×(l+b) ⇒P=2×(120 m+80 m) ⇒P=400 m Total distance covered by Paul, D= (Number of laps) × (Perimeter of the park) ⇒D=n×P ⇒D=3×200 m ⇒D=600 m Hence, the total distance covered by Paul would be 600 m.
