Question

A gardener planted 1521 trees in a rows such that the number of rows was equal to the number of plants in each row. Find the number of rows.​

Answer 1

Answer:39

Step-by-step explanation:

Let the no.of trees in each row =x

Let the no.of rows=x

∴ total no.of trees =x

2

⇒x 2=1521

∴x= 1521

​= 39×39

=39

∴ no.of rows =39

Hence, no.of trees in each row =39

Answer 2

Given that:-

number of trees = 1521

number of rows = number of plants in each row.

To Find :-

number of rows

As we know that,

Total number of trees = Number of rows × Number of trees in each row

Solution :-

Let,

the number of rows = number of plants in each row = n

put the value in formula

=> 1521 = n × n

=> $1521 = n^2$

=> $\sqrt{1521} = n$

=> n = 39

no. of rows = 39
