The expression to calculate the area of the structure is,
[tex]\begin{gathered} A=14\times11+\frac{1}{2}\times(14-5)\times(18-11) \\ =154+\frac{1}{2}\times9\times7 \\ =154+31.5 \\ =185.5cm^2 \end{gathered}[/tex]Thuss, the total area of the structure is 185.5 square centimeter. And the correct option is the fourth option.
