Answer:
4 feet on each side.
Step-by-step explanation:
Given :
Width of the wall = 11 feet
Width of the window = 3 feet
Now for the window to be placed in the center of window :
[tex]$=\frac{11-3}{2}$[/tex]
[tex]$=\frac{8}{2}$[/tex]
= 4 feet
Therefore, in order to place the window on the center of the wall, 4 feet space must be there on each side of the window.
