Answer:
Area of the floor not covered = 240ft²
Explanation:
Find the diagram attached
The area of the floor not covered = area of the office floor - area of the rug covered
Area of the office floor = 7in×5in = 35in²
Area of the rug = 5in×4in = 20in²
Area of the floor not covered = 35in²-20in² = 15in²
Since 1in = 4ft
1in² = 16ft²
Given the area of the floor not covered to be 15in²
In square feet will be 16×15 = 240ft²
