It helps immeasurably to know that 9 inches is the same as 3/4 of a foot.
And also that 3/4 is the same as 0.75 .
Then you have
(15.75 feet) x (6.75 feet) = 106.3125 square feet
Convert the inches to feet and you get 1.25. Multiply the two numbers and you get 16.25 square feet.
Convert each dimension to inches [15 * 12 + 6 = 186 inches and 12 * 12 + 8 = 152 inches] then multiply [186 * 152 = 28272] and then divide by 144 [28272 / 144 = 196.3recurring]. Assuming there are 12 inches in a foot.
Convert measurements to yards and then multiply them
32,100 square inches.
15x9 = 135 square feet
Convert the inches to feet and you get 1.25. Multiply the two numbers and you get 16.25 square feet.
3,510 square feet. This problem can be done by first converting both amounts to inches (multiply feet by 12), which would give the two amounts 180 inches by 234 inches. Multiply them together to receive square inches, then divide by 12 to convert it back to square feet.
Convert each dimension to inches [15 * 12 + 6 = 186 inches and 12 * 12 + 8 = 152 inches] then multiply [186 * 152 = 28272] and then divide by 144 [28272 / 144 = 196.3recurring]. Assuming there are 12 inches in a foot.
15 square feet
Convert the inches into feet and then multiply: 10/12 times 15/12 = 1.0416...recurring 6 square feet
Convert measurements to yards and then multiply them
If that's 15 inches by 22 inches, then it's 2.292 square feet. If it's 15 inches by 22 feet, or 15 feet by 22 inches, then it's 27.5 square feet. If it's 15 feet by 22 feet, then it's 330 square feet.
32,100 square inches.
15x9 = 135 square feet
15 square feet.
15 square feet is 2,160 square inches.
4.6m converts to 15 feet 1⅛ inches.
