Answer
To calculate the final BMI, we use the formula:
BMI=height (m)2weight (kg)
For patient T:
Weight = 94 kg
Height = 1.90 m
So,
BMI=(1.90)294=3.6194≈26.0
Thus, the final BMI for patient T is approximately 26.0.

Answer
Rugby players often have a relatively high muscle mass, which can lead to a higher BMI. Therefore, a BMI reading may not accurately reflect their body fat percentage, as muscle is heavier than fat. Muscle tissue adds weight without indicating an excess of body fat.
