In an auditorium, the number of rows is equal to the number of chairs in each row. If there are 5184 chairs in total. how many rows are there?
Let the number of rows be x.
A stated in question,
No.of rows$$ =$$ No.of chairs
Total Chairs $$ = 5184$$
So,
$$x^2=5184$$
$$x= \sqrt{5184}$$
$$x=72$$
So the no.of rows$$=72$$
