Explanation:
Required area = Area of rectangle with dimensions 16 ft and 6 ft + Area of trapezoid with bases (16 - 2 = 14) 14 ft, 10 ft and height 3 ft.
\begin{gathered} = 16 \times 6 + \frac{1}{2} (14 + 10)3 \\ \\ = 96 + \frac{1}{2} \times 24 \times 3 \\ \\ = 96 + 12 \times 3 \\ \\ = 96 + 36 \\ \\ = 132 \: {ft}^{2} \end{gathered} 
=16×6+
