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

\(123456789+987654321=1111111110\)

The sum of interior angles of a pentagon is: \(\left(5-2\right).180°=3.180°=540°\)
