Given:
The objective is to write a polynomial equation for perimeter of the given figure.
From the given figure the opposite sides are equal.
Then, the perimeter is the sum of all sides of the figure.
![\begin{gathered} P=3x-5+4x+3+4x+3+9+9 \\ =11x+24-5 \\ =11x+19 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/q3862ey7sbd2pdtn2h8pjc23gxwqcvylwx.png)
Hence, the polynomial that represents the perimeter of the figure is 11x+19.
