First, we need to find the scale factor between the scale drawing and the actual dimensions.
Scale factor = Actual length / Scale length
Scale factor = 32 feet / 8 inches = 4
Next, we need to apply the scale factor to find the actual width of the floor.
Actual width = Scale width x Scale factor
Actual width = 5 inches x 4 = 20 feet
Now, we can calculate the actual area of the floor:
Actual area = Actual length x Actual width
Actual area = 32 feet x 20 feet = 640 square feet
Therefore, the actual area of the floor is 640 square feet.
