The area of the trapezoid is the sum of the areas of the rectangle and the two triangles. Then, the area of the rectangle is:


A_{\text{rect}}=14\cdot12=168in^2

And the area of each triangle is:


A_{\text{triangle}}=(12\cdot2)/(2)=12in^2

The area of the trapezoid is:


\begin{gathered} A_{\text{Trapezoid}}=A_{\text{rect}}+2\cdot A_{\text{triangle}}=168+2\cdot12 \\ \therefore A_{\text{Trapezoid}}=192in^2 \end{gathered}
