#### Answer

$$A = 91$$

#### Work Step by Step

We are trying to find $A$ given values for $a$, $b$, and $h$:
$$A = \frac{1}{2} \times 7(10 + 16)$$
Simplify what is in parentheses first:
$$A = \frac{1}{2} \times7 (26)$$
Do the multiplication:
$$A = \frac{1}{2} (182)$$
Multiply $\frac{1}{2}$ by $182$:
$$A = 91$$
