The scale of the drawing is 8 inches by 5 inches, which means 8 inches represents 32 feet. Therefore, 1 inch represents 4 feet.
The actual dimensions of the floor are 32 feet by (5/8)*32 = 20 feet.
The actual area of the floor is 32 feet * 20 feet = 640 square feet.
Therefore, the actual area of the floor is 640 feet2.
