Answer» Speed of flowing of water from canal is 10km/h , means length of water flows in 1 hour = 5 km , so length of water flows in 30 minutes = 5km Now, volume of water flowing from canal = length of water flows in 30 minutes × breadth of canal × deep of canal = 5000m × 6m × 1.5m = 45000 m³ Let area of field = x m² Then, volume of water irrigates into the field = area of field × height of water during irrigation = x m² × 8× 10⁻² m = 0.08x m³ Now, volume of water flowing from canal = volume of water in field 45000 m³ = 0.08x m³ x = 562500 m² We know, 1 hectare = 10000 m² So, area of field in hectare = 562500/10000 = 56.25 hectares |
