Answer:
80ft
Step-by-step explanation:
A=LxW
L=12
W=8
12x8=96ft.
Area = 96ft (without the window.)
Now we need to subtract the window from the area from the wall. What is the area of the window?
A=LxW
L=4
W=4
4x4=16
A=16ft (Area of just the window)
Let's subtract the window form the wall to get the total area!
96-16=80ft
A=80ft
