ANSWER
Breadth = 1.5m, Depth/height = 6m, speed = 10km/h
length of canal in 1 hour = 10km
length of canal in 30 min =
60
30×10
=5km=5000m
Volume of canal =l×b×h=5000×1.5×6m
3
Volume of water in canal = Volume of area to be irrigated
⇒5000×6×1.5= Area irrigated × height
⇒Area irrigated =
8
45000×100
{∵h=
100
8
m}
⇒Area irrigated =562500m

=56.25 hectares
