Answer

$\frac{7}{32} \ \text{ft} ^2$.

Work Step by Step

The area is computed by $A = a \cdot b$. Here, we substitute $a = \frac{7}{8}$ and $b=\frac{1}{4} $. From this it follows that the area $A$ is computed by: $A = a \cdot b = \frac{7}{8} \cdot \frac{1}{4} = \frac{7 \cdot 1}{8 \cdot 4} = \frac{7}{32}$. With considering the unit, the answer is $\frac{7}{32} \ \text{ft} ^2$.
