Required:

To find the perimeter and area hallway.

Step-by-step explanation:

Area :


\begin{gathered} A=lw \\ \\ =(11y+1)(y-7) \\ \\ =11y^2-77y+y-7 \\ \\ =11y^2-76y-7 \end{gathered}

Perimeter :


\begin{gathered} P=2(l+w) \\ =2(11y+1+y-7) \\ =2(12y-6) \\ =24y-12 \end{gathered}

Final Answer:

Area :


11y^2-76y-7

Perimeter :
