For this case we have that by definition, the area of a rectangle is given by:
[tex]A = a * b[/tex]
Where:
a, b: They are the dimensions of the rectangle.
In the statement we are told that "The area is greater than 12 square inches", then:
[tex]A> 12[/tex]
Also we have:
[tex]a = 2\\b = x[/tex]
Substituting we have:
[tex]2x> 12[/tex]
Dividing between 2 on both sides:
[tex]x> \frac {12} {2}\\x> 6[/tex]
Finally we have:
[tex]x> 6[/tex]
ANswer:
[tex]x> 6[/tex]
