The Area of a Parallelogram.
The formula for area of a parallelogram is given below:
[tex]\begin{gathered} \text{Area = }bh \\ \text{where b = base = 8m} \\ h\text{ = height = x m} \\ \text{Area = 148 m}^2 \end{gathered}[/tex]Substituting these values into the formula, we get
[tex]\begin{gathered} 148=8\times x \\ 148\text{ = 8x} \\ \text{Dividing both sides by 8, we get} \\ x\text{ = }\frac{148}{8} \\ x=18.5\text{m} \end{gathered}[/tex]Therefore, the correct answer is 18.5m
