1ft = 12 in
1in = 2.54 cm
1 cm = 0.01 m
(6*12*2.54*0.01)*(3*12*2.54*0.01) = 1.67 m**2
1.67 m**2 != 21 m**2
21 square feet
The square root of 21 is 4.58257569495584.
Area of any circle = (pi) x (radius)2Radius = 1/2 of the diameterArea of the placemat = (pi) x (21)2 = 441 pi = 1,385.4 square centimeters = 0.13854 square meter
It is: 2 times the square root of 21 and it's an irrational number
plus or minus 21
Convert the feet and inches into metres and then multiply

21 square feet (7'x3') = 1.95 square meters.
"Cubic meter" is a unit of volume or capacity, as of a box, a bottle, or a balloon. "Square meter" is a unit of area or coverage, as of a bedroom floor, or a garden plot. The two units have different dimensions, and are used to measure different quantities. Neither can be converted to the other. It would be like trying to convert your age to gallons.
The answer would be 210 square meters.

273 square feet. Multiply length by width - the result is the area in square feet.
length x width = sq ft
There are 1/0.048906 = 20.45 So 20 pieces is not enough to cover 1 sq metre while 21 is. Alternatively. 20 pieces can fit in 1 sq metre but 21 will be too many.
I assume you mean a rectangle. You can:* Convert everything to feet, then multiply; or: * First multiply, then divide the result (which is in square inches) by 144, to convert to square feet.
1 sq. ft. = 0.092903 sq. m 21 square feet = 1.950963 square meters
