Type 2 diabetes is associated with being obese - Edexcel - GCSE Biology - Question 4 - 2016 - Paper 1

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

$\text{BMI} = \frac{\text{mass in kilograms}}{(\text{height in metres})^2}$

Substituting the given values:

• Mass = 90 kg
• Height = 1.50 m

We first calculate the square of the height:

$1.50^2 = 2.25$

Now, substituting into the BMI formula:

$\text{BMI} = \frac{90}{2.25}$

Calculating this gives:

$\text{BMI} = 40$
