the perimeter is 36
Step-by-step explanation:
This product could be zero if one or both of the parenthesis are zero.
3x-9=0; 3x=9; x= 3
5x-3=0; 5x=3; x=3/5
The solution is { 3/5, 3}
We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.
SO the length of rectangular window is

feet.
Width of the rectangular window is =

feet.
In general parameter of rectangle is =

So the parameter of window is =

So the required length of wood to frame window is = 28.834 feet
5^4 (five to the 4th power)
