42 ft x 30 ft = 1,260 square ft1 yd = 3 ft(1 yd x 1 yd) = 1 square yd = (3 ft x 3 ft) = 9 square ft.1,260 square ft = (1,260 / 9) = 140 square yards
11 feet by 9 feet is 99 square feet. A square yard is 9 square feet, so there are 11 square yards in 99 square feet.
5 ft by 9 ft is 45 square feet. This requires 6,480 square inches to cover it.
500 / (9 x9) = 6.17 so round up to 7ft

81 square feet, which is about 7.525 m2.
9 ft by 9 ft = 81 square feet 81 square feet = 7.52515 square meters.
(9-ft x 12-ft) = 108 square feet / (9 square feet per square yard) = 12 square yards======================Another method:9-ft = 3 yards12-ft = 4 yards(3yd x 4yd) = 12 square yards
87.75 square inches
9 × 9 = 81 square feet
Assuming 15 ft and 9 ft, the answer in 135 sq ft
42 ft x 30 ft = 1,260 square ft1 yd = 3 ft(1 yd x 1 yd) = 1 square yd = (3 ft x 3 ft) = 9 square ft.1,260 square ft = (1,260 / 9) = 140 square yards
11 feet by 9 feet is 99 square feet. A square yard is 9 square feet, so there are 11 square yards in 99 square feet.
9 ft x 9 ft = 81 ft2.
5 ft by 9 ft is 45 square feet. This requires 6,480 square inches to cover it.
