b of the canal=6m
h of the canal=1.5m
the speed of water in canal=10km/h
30 mins=30/60=1/2h
length of water=1/2x10=5km=5000m
h of irrigated area =8cm=8/100m=2/25m
v of water in canal =v of water required for irrigation
lxbxh=lxbxh
5000x6x1.5=lxbx2/25
lxb=[5000x6x1.5x25]/2
=562500
therefore the irrigated area=562500m2
h of the canal=1.5m
the speed of water in canal=10km/h
30 mins=30/60=1/2h
length of water=1/2x10=5km=5000m
