Question

The area of a square field is 325 m². Find the approximate length of one side of the field.

Answer 1

The length of one side of the square field will be the square root of 325.
$\therefore$ $$\begin{gathered} \sqrt{325}=\sqrt{5\times 5\times 13} \\ =5\times \sqrt{13} \\ =5\times 3.605 \\ =18.030 \end{gathered}$$

Hence, the length of one side of the field is 18.030 m.
