Question

The area of a square field is $325m^2$.Find the approximate length of one side of the field.

Answer 1

Area of a square field = $325m^2$

$\therefore Lengthofoneside=\sqrt{Area}=\sqrt{325}m=\sqrt{325}=\sqrt{25\times 13}=\sqrt{25}\times \sqrt{13}=5\times \sqrt{13}=5\times 3.606m\left(fromthetable\right)=18.030=18.030m$
