Respuesta :

The points are provided in the question to be:

[tex]\begin{gathered} L=(0,-8) \\ M=(5,-8) \\ N=(9,0) \\ O=(4,0) \end{gathered}[/tex]

The parallelogram is drawn below:

By the definition of a parallelogram, the opposite sides have the same lengths. Therefore:

[tex]\begin{gathered} LO=MN \\ ON=LM \end{gathered}[/tex]

Recall the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

Applying the formula to the lines of the parallelogram, the lengths are:

[tex]\begin{gathered} LO=MN=8.94 \\ ON=LM=5 \end{gathered}[/tex]

Therefore, the perimeter of the shape will be:

[tex]Perimeter=2(8.94+5)=27.88[/tex]

The perimeter is approximately 27.9 units.
