For this case we have that by definition, the perimeter of a rectangle is given by:

[tex]P = 2a + 2b[/tex]

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

We have as data that:

[tex]P = 230 \ ft\\b = 30 \ ft[/tex]

Then, replacing we have:

[tex]230 = 2a + 2 (30)[/tex]

Answer:

Option B
