Given:
Area of painting section = 1 m²
Suppose the completed part of the mural is
[tex]\frac{3}{4\text{ }}\text{ meter wide and }\frac{2}{5}meter\text{ long}[/tex]
this implies that the area of the completed section is evaluated as
[tex]\begin{gathered} \text{length }\times\text{ width} \\ =\text{ }\frac{3}{4}\text{ }\times\text{ }\frac{2}{5} \\ =\text{ }\frac{6}{20} \end{gathered}[/tex]
