HEY MATE!!! ❤❤HERE'S UR ANSWER!!! ❤❤
9 hectare = 9 × 10⁴ m²
Side length of square field = √(Area)
= √(9 × 10⁴ m²)
= 3 × 10² m
= 300 m
= 0.3 km
Time = Distance / Speed
= 4L / v
= (4 × 0.3 km) / (6 kmph)
= 0.2 hour
= 12 minutes
It takes 12 min for her to walk round the boundary for once.
HOPE THIS HELPS YOU!!! ❤❤❤
