Answer:


P\text{ = 29x+5}

Step-by-step explanation:

Here, we want to get the perimeter of the rectangle

Mathematically, that is:


P\text{ = 2(L + B)}

Where L is the length of the rectangle, given as 6.5x + 9 ft and B is the width of the rectangle which is 8x-6.5

Substituting these values into the formula, we have the perimeter of the rectangle as follows:


\begin{gathered} P=2(6.5x\text{ + 9 +8x-6.5)} \\ P\text{ = 2(14.5x+2.5)} \\ P\text{ = 29x+5} \end{gathered}
