 Feb 17, 2011 Math - Unit Conversion - Perimeter by: Staff The question: by Sijjila (London) a peson rnns around a field 10 time. he works out that runs 6km. what is the perimeter of the field in meters. The answer: The perimeter is the distance around the field. The person in your question has run around the field ten times. The total distance run is 6 km. To find the perimeter of the field in km, divide 6 km by 10. Perimeter = 6 km/10 = 0.6 km The perimeter of the field is 0.6 km. Convert the 0.6 km to meters: 1 km = 1000 meters To find the distance in meters, multiply 0.6 km x 1000 meters per km Distance in meters = (0.6 km) x (1000 meters/km) Note that the units “km” in the numerator cancel with the units “km” in the denominator. The final answer contains only the unit “meters” when the multiplication is completed. Distance in meters = (0.6 km) x (1000 meters/km) Distance in meters = (0.6 * 1000 meters) x (km/km) Distance in meters = (0.6 * 1000 meters) x (1) Distance in meters = 0.6 * 1000 meters * 1 Distance in meters = 0.6 * 1000 meters Distance in meters = 600 meters The final answer is: Perimeter = 600 meters You can check the conversion calculations with this free on-line calculator: http://www.unitconversion.org/unit_converter/length.html Click kilometer [km] in the left hand column Click meter [m] in the right hand column Enter 0.6 in “From” Box (top, left) Your answer in meters will automatically appear in the “To” Box (top, right) Thanks for writing.
