A hospital patient was tested for diabetes - Edexcel - GCSE Biology - Question 7 - 2021 - Paper 1

To calculate the Body Mass Index (BMI), we use the formula:

$$BMI = \frac{mass \ in \ kg}{(height \ in \ m)^2}$$

Substituting the values from Figure 10:

• Mass = 124 kg
• Height = 1.8 m

Calculating the height squared:

$$(1.8)^2 = 3.24$$

Now, substituting these values into the BMI formula:

$$BMI = \frac{124}{3.24} \approx 38.89$$

Thus, the BMI of the patient is approximately 38.89.
