For this case we have by definition, that the perimeter of the figure will be given by the sum of its sides, that is:

[tex]n + 3 + 6.3 + 4.5 = 18.6[/tex]

We add similar terms:

[tex]n + 13.8 = 18.6\\n = 18.6-13.8\\n = 4.8[/tex]

Thus, the correct option is option b. That is, [tex]4.8 \ in[/tex]

Answer:

[tex]4.8 \ in[/tex]

Answer: second option.

Step-by-step explanation:

The perimeter of the figure is the sum the lenghts of its sides.

You know that the perimeter of this figure is 18.6 inches.

You can observe that it has four sides and three lenghts are given.

Then, you can write this expression:

[tex]18.6in=3in+6.3in+4.5in+n[/tex]

Now you need to solve for "n" to calculate its value.

This is:

[tex]n=3in+6.3in+4.5in-18.6in[/tex]

[tex]n=18.6in-3in-6.3in-4.5in[/tex]

[tex]n=18.6in-13.8in[/tex]

[tex]n=4.8in[/tex]
