Step-by-step explanation:
................
For this case, the first thing you should do is take into account the following unit conversion:
1 foot = 12 inches
Therefore, the perimeter of the new window is given by:
p = 2w + 2l
Where,
w: width
l: long
Substituting values:
p = 2 * (3 + ((4 1/2) / 12)) + 2 * (4 + ((4 1/2) / 12))
p = 15.5 feet
Answer:
The new perimeter of the window in feet is:
p = 15.5 feet
