A person weighs 80 kg and is 1.60 m tall. What is the body mass index (kg divided by height in m squared)?
Answer and explanation
Correct answer: A. About 31.3
- Step 1: Height squared is 1.6 x 1.6 = 2.56. Step 2. 80 / 2.56 = 31.25. Answer: about 31.3. Why not the others: 50 divides by the height and 12.5 uses the wrong square.
