Answer:
BMI (body mass index) is a value derived from weight and height of a person.
Explanation:
take the weight of a person (in Kg) and his/her height (in metres). Then divide the weight by the square of the height. if the resulting value is from 18-25 there is no issue. A value of over 25 signifies being overweight and below 18 signifies malnourishment.
