The ceiling in Mitchell's bedroom measures 12 feet by 10 feet 11 inches. What's the total area of the ceiling in square inches?
The total area of the ceiling is 18,864 square inches.
Sol'n:
Convert both dimensions to inches:
12 feet = 12 × 12 = 144 inches
10 feet 11 inches = (10 × 12) + 11 = 120 + 11 = 131 inches
Area = length × width = 144 × 131
144 × 130 = 18,720
144 × 1 = 144
18,720 + 144 = 18,864 square inches
