A rectangular red carpet of size 6 ft ×12 ft has a dark red border 6 inches wide. What is the area of the dark red border?

Correct Answer: 17 square feet

Explanation:

Initially carpet is 6×12 = 72 sq feet

Since red border is 6 inches wide from all 4 side

So area without border = 5× 11 = 55 sq feet

Area of border = total–area without border = 72–55 = 17 sq feet
