Answer= 63 chairs in 63 rows!
Step-by-step explanation:
Subtracting 31 from 4000,we get 3969...
So if we want the no of rows to be equal to the no.of chairs, then the number should be a square of a particular number....
Therefore,
a=63x63=3969...
So to solve these questions you should simply find the square root...
