Step 1. Given information.

The given figure is given below as,

Step 2. Formula used.

The formula of area of trapezoid is defined as,

$Area = \frac{1}{2} \times (Sum of parallel sides) \times Height$

Step 3. Calculation.

Substitute the given values in the formula to find the remaining base.

$\begin{matrix} Area = \frac{1}{2} \times (7.5 + 19) \times 10.2 \\ = 26.5 \times 5.1 \\ = 135.15 {cm}^{2} \end{matrix}$

Step 4. Conclusion.

Therefore, the required area is $135.15 {cm}^{2}$ .
