The given diagram is shown in Figure 1

  

Figure 1

Calculation:

The wind shield is in the shape of the trapezoid and the area of the trapezoid is in the form,

  $A=\left(\frac{a+b}{2}\right)h$

Then,

  $\begin{array}{c}A=\left(\frac{72+35}{2}\right)\left(38\right)\\ =\left(23.5\right)\left(38\right)\\ =91.5{\text{ft}}^2\end{array}$
