Given:
The rectangle has the following dimensions
[tex]\begin{gathered} l=9x-4 \\ b=5x+2 \end{gathered}[/tex]Perimeter is the sum of the sides of a shape.
The rectangle has two lengths and two breadths
The perimeter of the rectangle is the sum of the four sides
[tex]\begin{gathered} P=(9x-4)+(9x-4)+(5x+2)+(5x+2) \\ \text{Collecting the like terms,} \\ P=9x+9x+5x+5x-4-4+2+2 \\ P=28x-4 \end{gathered}[/tex]Therefore, the perimeter of the rectangle is 28x - 4.
