Explanation:

Given
Water is flowing at a speed of = 10 km / hr
In 20 minutes length of the flowing standing water = 10*30/60 = 5 km = 5000 m
Width of the canal = 1.5m
Depth of the canal = 6m
Volume of water in 20 minutes = 5000 * width * depth = 45000 m³
Irrigated area in 20 minutes if 5 cm of standing water is desired = 45000 / 0.08 m2 = 562500 m²
Irrigated area in 30 minutes is 562500 m²
