Question 10(a)(i)

[Maximum number: 2]

The body mass index (BMI) is a measure that uses your mass and height to calculate if your mass is appropriate for your height.

BMI is calculated using the formula

BMI= mass in kg÷( height in m)2\mathrm{BMI}=\text { mass in } \mathrm{kg} \div(\text { height in } \mathrm{m})^{2}

Person X has a mass of 60 kg and a height of 165 cm .
