60 seconds in a minute
12 goes into 60, 5 times,
So 5 * 28 = 140
140 claps per minute
0.5 minute is 30 seconds, half a minute so divide by 2,
140/2 = 70
70 times every 0.5 minutes
Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!
