The area of the original rectangle is 2 feet x 3 feet = 6 square feet.
The area of the rectangular area removed is 8 feet x unknown width = 8w square feet.
Therefore, the remaining area is 6 square feet - 8w square feet = 36 square feet.
Solving for the unknown width:
8w = 6 - 36
8w = 30
w = 30/8
w = 3.75 feet
Therefore, the side labeled with the question mark is 3.75 feet.
