A gardener plants 17956 trees in such a way that there are as many rows as there are trees in a  row. The number of trees in a row is

(a) 134

(b) 136

(c) 144

The number of trees in each row.

$\large{\underline{\rm{\purple{\bf{Solution:-}}}}}$

Given that, the total number of trees the gardener plants = 17956 trees

Let us consider the number of rows as x

According to the question,

$\sf x \times x=17956$

$\sf x^{2}=17956$

$\sf x=\sqrt{17956}$

$\sf x=\sqrt{(2 \times 2 \times 67 \times 67)}$

$\sf x=2 \times 67$

$\sf x=134$

∴ Number of rows = 134

Therefore, there are 134 number of rows.
