Answer:
90
Step-by-step explanation:
Given that :
Number of soldiers = 8160
Number left out = 60
Result of arrangement gives a perfect square ;
Hence, the number of soldiers which makes up the arrangement will be ;
Total number of soldiers - number left out
8160 - 60 = 8100
Hence 8100 soldiers were used to form a perfect square ;
Number of soldiers in a row :
√8100 = 90
Hence, we have 90 soldiers in a row
