Question

A gardener wants to plant $17956$ trees and arranges them in such a way that there are as many rows as there are trees in a row. What is the number of trees in a row?

• A. $144$
• B. $136$
• C. $154$
• D. $134$

Answer 1

Answer: (D)

$134$

Let the number of rows $=x$
Number of columns $=x$
Total trees $=17956$
$x\times x=17956$
$x²=17956$
$x=\sqrt{17956}$
$x=\sqrt{(2\times 2\times 67\times 67)}$
$x=2\times 67$
$x=134$
Therefore, the number of trees on a rows $=134$.
