Given:
a.) A rectangle with 4 inches as its height and 1 inch as its length.
To be able to find the perimeter, we will be using the following formula:
[tex]\text{ Perimeter = 2L + 2H}[/tex]Where,
L = Length
H = Height
We get,
[tex]\begin{gathered} \text{ Perimeter = 2L + 2H} \\ \text{ = 2(1) + 2(4)} \\ \text{ = 2 + 8} \\ \text{ Perimeter = 10 inches} \end{gathered}[/tex]Therefore, the perimeter of the rectangle is 10 inches.
