Question

In a hall with length 25 m and breadth 13m students have to be seated when the distance between two adjacent seats should be atleast 2m . i. How many rows can be there in the hall and how many seats in each row? ii. What will be the maximum capacity of the hall?(student can solve using a graph sheet or numerically) iii. If seating for twice the number of students have to be arranged in another Hall with length 37m ,what will be the minimum width of this hall?

Answer 1

Step-by-step explanation:

Given :  In a hall with length 25 m and breadth 13m students have to be seated when the distance between two adjacent  seats should be atleast 2m  

To find :  How many rows can be there in the hall and how many seats in each row .  maximum capacity of the hall

Solution:

hall with length 25 m  

2 m distance between two seat

number of rows =  13  

Breadth = 13 cm

=> Number of seats in a row =  7

Maximum capacity of Hall  = 13 * 7 = 91

Seating twice the number  = 2 * 91 = 182 Students

length 37 m  => rows = 19

Seats in each row  182/19  > 9  = 10

Hence 19 m  Width is required.
