Respuesta :

The area of the garden is

[tex]2(5.5x+3.5)[/tex]

and the combined area is:

[tex]2.5(8x+5)[/tex]

To find the area of the walkway we substract the area of the garden to the combined area, that is:

[tex]\begin{gathered} 2.5(8x+5)-2(5.5x+3.5)=20x+12.5-11x-7 \\ =9x+5.5 \end{gathered}[/tex]

Therefore the area of the walkway is:

[tex]9x+5.5[/tex]
