Question

the number of people in a row is equal to the number of rows in a play ground.if the number of people in the playground is 19044.then find number of rows

Answer 1

Let,

No.of people in a row=number of rows=x

Then,

Total no.of people=x*x=x^2

But given that,

Total no.of people=19044

Then,

19044=x^2

x=√19044

x=138

.

. ..No of rows=x=138

hope it helps
