Work Step by Step
Find the area of each wall, of the window, and of the door.
$A_1=bh=12\times8=96$
$A_2=bh=12\times8=96$
$A_3=bh=10\times8=80$
$A_4=bh=10\times8=80$
$A_d=bh=3\times7=21$
$A_w=bh=6\times5=30$
Find the total wall area.
$A=A_1+A_2+A_3+A_4=96+96+80+80=352$
Find the total area of the window and door.
$A=A_w+A_d=30+21=51$
Deduct the area of the window and door from the total wall area.
$A=352-51=301$
