Question

There are 47 rows of seats in a cinema hall. 29 people can be seated in each row. How many people can be seated in the hall ?

Answer 1

Hint:Suppose there are ‘n’ number of rows with ‘m’ number of elements in each row then the total number of elements in the arrangement is equal to $m\times n$. Use this formula to calculate the number people that can fit in the given cinema hall.

Complete step by step answer:
If you have ever been to a cinema hall then you must have observed how the seats in the hall are arranged. We say that they are arranged in some rows and columns.Rows are the arrangement of objects or people along some parallel straight lines. These lines are mostly horizontal and the number of elements in each row or the horizontal straight lines is equal. Once we arrange the objects in rows, the arrangement along vertical straight lines are called columns.

We can say that an arrangement in the form of rows and columns resembles a rectangle, which is different in equal divisions.Suppose there are ‘n’ number of rows with ‘m’ number of elements in each row than the total number of elements in the arrangement is equal to $m\times n$.Here, it is given that there are 47 number of rows and 29 number of seats in each row. This means that $m=47$ and $n=29$.

Therefore, the total number of people that can be seated in the cinema hall is equal to $47\times 29=1363$.

Note:If that are ‘n’ number of rows and ‘n’ number of columns in the arrangement than the total number of elements in the arrangement is equal to $m\times n$.Note that the number of columns is equal to the number of elements in each row.And the number of rows is equal to the number of elements in each column.
