Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! by breadth, i assume you mean width.
if the area is 42 square meters and the length is 2000 centimeters, then you can find the width by dividing the area by the length.
42 square meters is equal to 420,000 square centimeters.
the length would therefore be equal to 420,000 / 2000 = 420 / 2 = 210 centimeters.
210 centimeters times 2000 centimeters is equal to 420,000 square centimeters.
420,000 square centimaters divided by 10,000 square centimeters per squere meters becomes equal to 42 square meters.
the conversion factor for square meters to square centimeters is equal to 10,000.
1 square meter is equal to 10,000 square centimeters.
this is easy to see when you convert meters to centimeters.
1 meter is equal to 100 centimeters.
1 square meter is equal to 1 * 1 = 1 square meter.
100 centimeters * 100 centimeters is equal to 10,000 square centimeters.
i believe your error has to do with conversion of square meters to square centimeters.
take into consideration that 42 square meters is actually equal to 420,000 square centimeters and you should be ok.
you can convert all to centimeters or you can convert all to meters.
42 square meters / 2000 centimeters is equal to 420,000 square centimeters / 2000 centimeters which is equal to a width of 210 centimeters which can be converted to 2.1 meters.
42 square meters / 20 meters is equal to 2.1 meters which can be converted to 210 centimeters.
it is true that there are 100 centimeters to a meter.
however, there are 10,000 square centimeters to a square meter.
