Length of the Rectangle = 5x+2
Width of the rectangle = 6x+8
Perimeter of a rectangle = 2(Length + Width )
Therefore:
[tex]\begin{gathered} \text{Perimeter}=2(5x+2+6x+8) \\ =2(5x+6x+2+8) \\ =2(11x+10) \\ =22x+20 \end{gathered}[/tex]The perimeter of the rectangle in simplified standard form will be:
[tex]Perimeter=2(11x+10)\text{ Units}[/tex]
