Answer

$9 \ \text{m} ^2$.

Work Step by Step

The area is computed by $A = a \cdot b$. Here, we substitute $a = 12$ and $b=\frac{3}{4} $. From this it follows that the area $A$ is computed by: $A = a \cdot b = 12 \cdot \frac{3}{4} = \frac{12}{1} \cdot \frac{3}{4} = \frac{3}{1} \cdot \frac{3}{1} = \frac{3 \cdot 3}{1} = \frac{9}{1} = 9$. With considering the unit, the answer is $9 \ \text{m} ^2$.
