Question

an auditourm has to filled with 228 how many chairs needed in each row if there is 7 row in total how many chairs are extra​

Answer 1

Answer:

Step-by-step explanation:

let chairs in row be x

so number of rows also , x

total number of chairs = x * x

= x^2

there are 7033 students in school and each student gets chair . some chairs leaves empty  

so , x^2 > 7033 , such that x^2 is not exceeds than 7033 + 31 = 7064

so finding the square number just below 7064  

80^2 = 6400

90^2 = 8100

the number is between 80 and 90

now 85^2 = 7225

so expected number is below 85

83^2 = 688984^2 = 7056

so x^2 = 7056 = 84^2

which is total number of chairs in auditorium

so 7056 - 7033 = 23

23 chairs remains empty
