A square kilometer is just an area that is both wide and tall in kilometers. A kilometer is 1000 meters. So let's say for instance you had a field that was 5 kilometers by 10 kilometers, the total area of the rectangular field would be 50 SQUARE kilometers because the two sides are being multiplied.
The answer may vary. If you take a square away from the field it will still have the same perimeter. So the Length and Width may vary on how you make the field.
meters
The dimensions are 7 by 12 meters Check: perimeter = 2*(7+12) = 38 meters and area = 7*12 = 84 square meters
kilometers
8,536 square meters
Square meters are a measure of area, not length.
The field covers 7,140 square meters.
An American football field is 109.728 meters long (120 yards) by 48.768 meters wide (53 1/3 yards). That makes the field 5,531.2151 square meters.
The length is 10 meters and the width is 5 meters
The area of Field Dalling is 12.87 square kilometers.
