First, let's convert 1 1/3 to a decimal.
[tex]1/3 * 100 = 33.3[/tex]
Decimal moves 2 to the left, making it 0.33
Now we know the width is 1.33 feet.
Area = length * width
Because of this, we know that:
area/width = length
So, we can plug in the appropriate values
[tex]14/1.33 = 10.52[/tex]
The length of the rectangle is 10.52 feet.
