Approx 13.4 square metres.
9 ft * 7 ft = 63 sq ft = 5.85 sq metres
9' * 11' = 99 sq ft = 9.20 sq metres.
14 ft x 9 ft = 126 sq ft = 126 x .0929 m2 = 11.7 m2 (approx)
10 ft * 16 ft = 160 sq ft = 160/9 = 17.77.. recurring sq yards. 10 ft * 16 ft = 160 sq ft = 160/9 = 17.77.. recurring sq yards. 10 ft * 16 ft = 160 sq ft = 160/9 = 17.77.. recurring sq yards. 10 ft * 16 ft = 160 sq ft = 160/9 = 17.77.. recurring sq yards.
9 (9) = 81 square feet
1 ft = 0.3048 metres so 9 ft = 2.74 metres Then 9 ft * 9 ft = 2.74 metres * 2.74 metres = 7.525 sq metres.
12 ft x 9 ft = 108 sq ft = 10.03 sq metres.
9 ft * 7 ft = 63 sq ft = 5.85 sq metres
12 in = 1 ft → 1 tile = 16 in × 16 in = (16 ÷ 12) ft × (16 ÷ 12) ft = 16/9 sq ft → 80 tiles = 80 × 16/9 sq ft = 1280/9 sq ft = 142 2/9 sq ft ≈ 142.22 sq ft
23 ft * 9 ft = 207 sq ft = 19.23 sq metres.
(13-ft x 16-ft) / (9 square feet per square yard) = (23 and 1/9) square yards
The square footage of 9 ft x 16 ft is 144 sq feet. But this assumes that the measurements are 9 ft x 16 ft and not 9 inches x 16 inches or some other units - an assumption that is in no way justified by the information in the question.
9 feet = 9*0.3048 metres = 2.7432 m So 9 ft * 9 ft = 2.7432 * 2.7432 m2 = 7.53 m2approx.
9' * 11' = 99 sq ft = 9.20 sq metres.
16" x 16" = (4/3 ft) x (4/3 ft) = 16/9 square footMultiply the cost of one tile by (9/16) = 0.5625to get the cost per square foot.
9 ft 6 in = 114 in = ( 114 * 25.4 / 1000 ) 2.8956 metres 8 ft 6 in = 102 in = ( 102 * 25.4 / 1000 ) 2.5908 metres So: 2.8956 * 2.5908 = 7.5019 square metres (approx)
10 ft 3 in * 9 ft = 10.25 ft * 9 ft = 92.25 sq ft = 8.57 sq metres approx.
