It is known that there are 7 fundamental units in S.I system .
Hence,By conversion table :
For unit of length and mass and conversion .
we can say that 1 m=100 cm .
So, using the relation we can get :
2.1 m =210 cm .
21 feet = 6.4 meters.
area = length by width. = 21 X 42 =882m2
21 feet long (6.4 meters)
21 meters long (69 ft), 33 tons
To convert from feet to meters multiply by 0.3048 21 feet = 21 x 0.3048 meters ~ 6.4 meters
21 miles = 33,796.2 meters
21 meters = 826.771654 inches
21 meters = 2,100 centimeters
A circle with a radius of 21 meters has a circumference of 131.95 meters.
Answer: 21 m = 68.8976 ' OR 68 ' and 10.77 "
21 meters is the same as about 68 feet 10.77 inches.
21 square meters is 226.04 square feet.
