It I'd 12 multiplied by 9 aka 108.
216 sq ft
12 x 9 = 108 ft2
9 x 11 = 99

Area of a circle = pi*radius2
Assuming the room is 9 ft by 14 ft (the question does not say so), the area would be 9*14 = 126 square feet
Assuming the room is 9 ft by 13 ft (the question does not say so), the area would be 9*13 = 117 square feet
