The formula for calculating the BMI of an individual is: BMI (kg/m 2 ) = 1.2.1 Use this formula to show how the BMI value of 23,7 kg/m 2 for a person with length 1,78 m and mass 75 kg was calculated. (2) 1.2.2 Use the BMI formula to determine the height for a person with a mass of 58 kg and BMI of 24,1 kg/m 2. Round off your answer to two decimal places. (3) 2
