Answer 1

Step-by-step explanation:

Let the number of chairs in each row be x.

Then, the number of rows = x.

Total number of chairs in the auditorium=(x)×(x)=xsq

But the number of chairs that the auditorium can accommodate = 1764 (given)

x(2)=1764

=2×2×3×3×7×7

x=2×3×7

=42

Hence, the number of chairs in each row is 42.
