Question

a gardener has 1000 plants he wants to plant in such a way that no. of rows and no. of column is same find the minimum no. of plants in each row ? square and square root lesson .

Answer 1

Let the rows be x
So the number of trees are equal x
So
${x}^{2}$
So
${x}^{2} = 1000$
X=
$\sqrt{1000}$
X = 10
So 10 trees in 10 rows

Answer 2

Let no. of rows be x
then,
according to question,
No. of rows should equal to no. of columns.

So,
no. of columns will also be x

then,

$x \times x = 1000 \\ {x}^{2} = 1000 \\ x = \sqrt{1000} \\ x = 31.62......$
Minimum should be 31
and (1000-961) = 39 plants will be left out in this arrangement.
