12.1 feet
Explanation
Step 1
Perimeter is the distance around the edge of a shape, the perimeter of a rectangle is given by
[tex]\begin{gathered} Perimeter(P)=\text{ 2}\cdot length(l)+2(width(w) \\ P=2(l+w) \end{gathered}[/tex]so
Step 1
Let
[tex]\begin{gathered} \text{length}=3.3\text{ ft} \\ \text{width}=2.75\text{ ft} \end{gathered}[/tex]now, replace in the expression
[tex]\begin{gathered} P=2(l+w) \\ P=2(3.3ft+2.75ft) \\ P=2(3.3ft+2.75ft) \\ P=2(6.05\text{ ft)} \\ P=12.1\text{ ft} \end{gathered}[/tex]therefore, the answer is
12.1 feet
