Heya Mate!!
Here is your answer!!
Solution:-
Angle described in 60 minutes = 360°
Angle described in 1 minute = 360/60 = 6°
Since length of minute hand is 12 cm, which is the radius of clock.
Area described in 35 minutes = (35*6)(*22/7*12*12)/360
= 264 sq cm (Answer)

angle covered by minute hand
in 5 min= 30°
in 30 min = 210°
area of sector = angle/360 * pi r^2
' ' =210/360 * 22/7* 144
=264 cm^2
in 5 min= 30°
