. Measurement uncertainty and Estimation or Fermi calculation: Consider average size of a soccer field with length of 100.0m and width of 75.0 m. a) If you measure the detentions by using a tape meter with cm/mm scale, write down the dimensions in standard method? [Values with measurement uncertainty] b) Calculate the area of the field and uncertainty of area? c) Consider average shoulder width of a person is 136 cm, and estimate how many people can stand on the field to cover the whole area of the field? [Hint: consider each person needs a circular area of radius r]
