Question

1521 trees planted in garden such way that there are many trees in each row asthree are rows in the garden find the number of each row

Answer 1

let the no of rows be x
so the no of trees in each row will also be equal to x
so total trees =x*x=x²
atq,
x²=1521
⇒x=39
..so there are 39 rows and 39 trees in each row.

Answer 2

let the no.f trees in each row =x
let the no.f rows=x
therefore total no.f trees =x raised to 2
x raised to 2 =1521
therefore x=39
there fore no.of rows =39
no.f trees in each row =39
