Answer:
3 ft^2
Explanation:
We'll assume the carpet is only for the closet floor. In that case we don't need the closet height.
Area of the floor can be calculated by multiplying the length (4 1/2 feet) and depth (2/3 foot):
Area = (4 1/2 feet)*(2/3 feet)
Area = (9/2 ')*(2/3 ')
Area = (18/6)'
Area = 3 ft^2
