Question

A gardener planted 1,521 trees in 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:

Total trees= 1,521

Let plants in each row =x

Let no. of rows = y

x = y

Total no. of plants = x*y

x*y=1,521

∵ x=y,   x² = 1,521

            x  =√1521

                =39

∴ The no of rows = 39

   and the no. of trees in each row = 39

Answer 2

A gardener planted 1,521 trees in rows such that the number of rows was equal to  the number of plants in each row. Find the number of row.

ANSWER = 39

Step-by-step explanation:

let the no. of trees (in each row) be X  and no. of rows be X

ATQ,

no. of  trees = no. of rows * no. of trees (in each row)

=> X*X=1521

=> X²=1521

=> X=√ 1521

=>   X=39
