As far as we know, no one ever has; the tallest person for which there is reliable documentary evidence was Robert Wadlow, who was 8 feet 11.1 inches tall (and still growing ... he was only 22) at the time of his death. The tallest person living today is 8 feet 3 inches.
Both of these had health problems related to their size. It seems unlikely that someone could survive to reach 11 feet tall.
216 inches / 11 feet = 18 feet/11 feet = 18/11
132 inches=11 feet
Feet and feet are the same measurement. Therefore, 11 feet is equal to 11 feet.
11 feet = 3 yards and 2 feet
121
11 x 10 feet = 110 square feet
3 feet = 1 yard therefore 11 feet = 3 yards 2 feet
11 feet by 12 feet = 11 x 12 = 132 square feet which is equivalent to 12.3 square meters.
It depends on how tall the 11 year old is. 120 pounds is a healthy weight for someone who stands 5 feet tall up to 5 feet 6 inches tall.
121 square feet.
10 ft * 11 ft = 10*11 = 110 square feet.
Multiply 10 by 11...
