hope this is helpful:
V=220V
I=5A
P = V×I
P= 220×5
P=1100W
t=2h=2×60×60=7200s
P=1100×7200=7.92×10^6J
Power of the motor is 1100W
Energy consumed by the motor is 7.92×10^6J

Explanation:
we know that
w=iv
work done= 1100J
and
p=w/t
t=2*60*60 second
t=7200 sec
power=1100/7200
11/72 watts
hope it helps you (•‿•)
