A patient weighs 64 kg and is 1.7 m tall. What is the body mass index?
Answer and explanation
Correct answer: C. 22.1 kg/m^2
- Step 1: BMI = weight in kg divided by height in meters squared.
- Step 2: BMI = 64 / 1.7^2 = 22.1.
Answer
22.1 kg/m^2.
Why not the others: Height must be squared; dividing by height alone or by height in centimeters gives other values.
