Given:
There are given the polygon and their sides.
Explanation:
According to the question:
We need to find the value of the perimeter of a given polygon.
So,
From the formula of the perimeter of the polygon:
[tex]P=addition\text{ of all sides}[/tex]
Then,
[tex]\begin{gathered} P=10m+10m+9m+9m+7m \\ P=45m \end{gathered}[/tex]
Final answer:
Hence, the value of the perimeter is 45
