By definition, the area of a Parallelogram can be calculated with the following formula:
[tex]A=bh[/tex]
Where "b" is the base of the parallelogram and "h" is the height.
In this case, according to the information given in the exercise, you know that:
[tex]\begin{gathered} b=12in \\ h=2.5in \end{gathered}[/tex]
Knowing these values, you can substitute them into the formula shown before:
[tex]A=(12in)(2.5in)[/tex]
Finally, evaluating, you get that the area of this Parallelogram is:
[tex]A=30in^2[/tex]
