15 ft

Explanation

you can easily solve this by using a rule of three

Step 1

Let x represents the actual length of the wall in feet

is

[tex]1\text{ inc}\rightarrow3\text{ ft}[/tex]

then

[tex]5\text{ in}\rightarrow x[/tex]

as the proportion is the same

[tex]\begin{gathered} \frac{1}{3}=\frac{5}{x} \\ \text{cross multiply} \\ x\cdot1=5\cdot3 \\ x=15\text{ ft} \end{gathered}[/tex]

so, the answer is 15 ft

I hope this helps you
