Question

The area of a square field is $30\frac{1}{4}{\mathrm{m}}^2.$ Calculate the length of the side of the square.

Answer 1

The length of one side is equal to the square root of the area of the field. Hence, we just need to calculate the value of .
We have:


Now, calculating the square root of the numerator and the denominator:



$\mathrm{Therefore},\mathrm{the}\mathrm{length}\mathrm{of}\mathrm{the}\mathrm{side}\mathrm{of}\mathrm{the}\mathrm{square}=\sqrt{30\frac{1}{4}}=\frac{11}{2}=5\frac{1}{2}\mathrm{m}$
