Answer 1

Answer:

Step-by-step explanation:

8..

If the General had 10 men less then the number would have been a perfect square.

So 64009 is the area of a perfect square.

64009=side²

side=√64009

      =253

The number of men in every row is 253

So number of men in the front row is also 253.
