Question

A gardener planted 1521 tree in rows such that the number of row was equal to the number of plant in each row find the number of rows
​

Answer 1

Answer:

The no. of rows is the no. of plants 1521.

Answer 2

Answer:

$no. \: of \: rows \: = \: x$

$no. \: of \: plants \: = \: y$

$x = y$

$xy = 1521$

$x \times 2 = 1521$

$taking \: sq. \: root \: on \: both \: sides \:$

$x = 39 \\ y = 39$

$hence \: , \: number \: of \: rows \: is \: equal \\ to \: the \: number \: of \: plants \: = \: 39$
