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?

9 square feet

15 square feet

17 square feet

18 square feet

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
