Because it's a square, so the area is \(\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}\left(m^2\right)\)

\(\dfrac{1}{3}\) area of that square has the value of \(\dfrac{1}{4}\cdot\dfrac{1}{3}=\dfrac{1}{12}\left(m^2\right)\)

Answer : \(\dfrac{1}{12}m^2\)

The area of the square is: \(\dfrac{1}{2}.\dfrac{1}{2}=\dfrac{1}{4}\left(m^2\right)\)

\(\Rightarrow\)\(\dfrac{1}{3}\) of the square have a area value is: \(\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{3}{4}\left(m^2\right)\)

                                       Answer: \(\dfrac{3}{4}\) m²
