Step by Step Solution

Step 1

We know that the perimeter can be calculated by adding up all the side lengths together. The picture below shows all the side lengths of the parallelogram.

Step 2

Logically, adding up all the side lengths together must result in 26ft. Hence:

Step 3

Now, we can simplify the equation as shown:

Step 4

To get a step closer in finding x, we add -16 to both sides of the equation. This is shown below:

Step 5

Next, to find x, we divide both sides of the equation with 2:

Step 6

Now, the calculated number, 5, has no meaning unless we include the unit for it. Since the perimeter is in feet, x will be in feet. Hence:
