A person's Body Mass Index is the ratio of the person's mass to the square of the person's height. mathematically, it is defined as;

. The universally accepted unit for BMI is kg/m²

BMI measurement classifies an adult as either underweight, normal weight, overweight or obese. Below are the normal ranges of the different weight categories;

underweight = <18.5 kg/m²

Normal weight = 18.5 - 25 kg/m²

overweight = 25 - 30 kg/m²

obese = >30 kg/m²

From the information in the question, for Andrew, we are given that;

weight = 190 lbs

height = 5 feet 10 inches

Now let us convert the height to inches;

1 foot = 12 inches

∴ 5 feet = 12 × 5 = 60 inches

∴ 5 feet 10 inches = 60 + 10 inches = 70 inches

Now BMI;

since the BMI is 27.3 kg/m², it fall in the category of overweight, as classified above
