Answer:
=> 216
Step-by-step explanation:
perimeter of the rectangular pool is
=> 2(l+b)
=> 2( 45.7 + 62.3 )
=> 2(108.0)
=> 216
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
