Answer:
28.2 ft²
Explanation:
Data provided in the question:
Length of the display floor, l = 4.7 feet
Width of the display floor, w = 6 feet
Therefore, 
The area of the floor space = l × w
on substituting the value in the above formula,
The area of the floor space = 4.7 × 6 
or
The area of the floor space = 28.2 ft²
Hence, the floor space needed for the display is 28.2 ft²
