The area of the shaded region can determined by substracting the area of rectangle from the area of triangle,
[tex]\begin{gathered} A=A_r-A_t \\ =14\operatorname{cm}\times25\operatorname{cm}-(\frac{1}{2}\times11\operatorname{cm}\times25) \\ =212.5cm^2 \end{gathered}[/tex]Thus, the area of the shaded region is 212.5 square centimeters.
