Given:
a.) A rectangular cardboard measures 8 inches x 11 inches.
To be able to find the area of the rectangular cardboard, we will be using the following formula:
[tex]\text{ Area = L x W}[/tex]We get,
[tex]\begin{gathered} \text{ Area = L x W} \\ \text{ = 8 x 11} \\ \text{Area = 88 in.}^2 \end{gathered}[/tex]Therefore, the area of the rectangular cardboard is 88 in.^2.
