The area of the shaded region is,

`\begin{gathered} Area\text{ }of\text{ }the\text{ }shaded\text{ }region=Area\text{ }of\text{ }the\text{ }rectangle-Area\text{ }of\text{ }the\text{ }triangle \\ =l* b-(1)/(2)* b* h \\ =5*9-(1)/(2)*4*3 \\ =45-6 \\ =39ft^2 \end{gathered}`

Hence, the area of the shaded region is 39ft^2.
