20 inch ^2

#### Explanation:

Area of shaded triangle = area of the whole triangle - area of unshaded triangle.

Area of the whole triangle $= \frac{1}{2} \cdot 12 \cdot 5 = 30 {\in}^{2}$

Area of unshaded triangle $= \frac{1}{2} \cdot 4 \cdot 5 = 10$ in^2

Area of shaded triangle $= 30 - 10 = 20$ in^2
