As per given by the question,
There are given a parallelogram, and their height and width.
Now,
Suppose height of the parallelogram is h and width of the parallelogram is b.
So,
[tex]h=9\operatorname{km},\text{ and b=18.5 km}[/tex]
According to the properties of parallelogram,
The opposite side are congruent.
Then,
Perimeter of the parallelogram is,
Perimeter= sum of all side
[tex]\begin{gathered} P=9+18.5+9+18.5 \\ =55\text{ km} \end{gathered}[/tex]
Now, area of the parallelogram,
The area of the parallelogram is,
[tex]\text{Area}=\text{height}\times width[/tex]
Here, height is 9 km and width is 18.5 km
So,
[tex]\begin{gathered} \text{Area}=9\times18.5 \\ =166.5\text{ km} \end{gathered}[/tex]
Hence, the perimeter of parallelogram is 55 km and area of parallelogram is 166.5 km
