Let's firstly calculate the perimeter of the drawing of the bedroom.
[tex]\text{perimeter(drawing) P}=2(l+b)[/tex]Given;
[tex]\begin{gathered} l=3.25\text{ inches} \\ b=4.75\text{ inches} \end{gathered}[/tex]So, the perimeter of the drawing is;
[tex]\begin{gathered} P=2(3.25+4.75) \\ P=2(8) \\ P=16\text{ inches} \end{gathered}[/tex]
