A rectangular garden has one side with a length of x + 7 another with a length 2x + 3
We are asked to find the perimeter of the garden
Let me draw this rectangular garden to better understand the problem
Recall that the perimeter of a rectangular shape is given by
[tex]P=2(W+L)[/tex]Where W is the width and L is the length of the rectangular garden
Let us substitute the given values into the above formula
[tex]P=2(x+7+2x+3)[/tex]Now simplify the equation
[tex]\begin{gathered} P=2(x+2x+7+3) \\ P=2(3x+10) \\ P=6x+20 \end{gathered}[/tex]Therefore, the perimeter of the rectangular garden is equal to 6x + 20.
