The Body Mass Index (BMI) is a measure used to assess whether a person has a healthy body mass for their height.
Table 1 shows information about two people, Person A and Person B.
| Person | Body mass in kg | Height in m | BMI in kg/m2\text{kg/m}^2kg/m2 |
|---|---|---|---|
| Person A | 54 | 1.62 | 20.6 |
| Person B | 88 | 1.68 | XXX |
Table 2 shows the standard BMI categories for adults:
| BMI Range (kg/m2\text{kg/m}^2kg/m2) | BMI Category |
