Calculate and classify the BMI for athletes A, B, C, and D using the provided height, mass, and BMI categories.

• Athlete A: $168 \text{ cm} = \frac{168}{100} \text{ m} = 1.68 \text{ m}$
• Athlete B: $175 \text{ cm} = \frac{175}{100} \text{ m} = 1.75 \text{ m}$
• Athlete C: $182 \text{ cm} = \frac{182}{100} \text{ m} = 1.82 \text{ m}$
• Athlete D: $160 \text{ cm} = \frac{160}{100} \text{ m} = 1.60 \text{ m}$

1.1.2 Calculate the BMI of each athlete using the formula $\text{BMI} = \frac{\text{mass (kg)}}{(\text{height (m)})^2}$.

• Athlete A:

$$\text{BMI}_A = \frac{62 \text{ kg}}{(1.68 \text{ m})^2} = \frac{62}{2.8224} \approx 21.97$$

• Athlete B:

$$\text{BMI}_B = \frac{78 \text{ kg}}{(1.75 \text{ m})^2} = \frac{78}{3.0625} \approx 25.47$$

• Athlete C:

$$\text{BMI}_C = \frac{95 \text{ kg}}{(1.82 \text{ m})^2} = \frac{95}{3.3124} \approx 28.68$$

• Athlete D:

$$\text{BMI}_D = \frac{52 \text{ kg}}{(1.60 \text{ m})^2} = \frac{52}{2.56} \approx 20.31$$

1.1.3 Refer to the BMI categories chart provided below to classify the BMI of Athlete C according to the given categories.
BMI Categories for Adults:
Underweight (<18.5)
Normal (18.5–24.9)
Overweight (25.0–29.9)
Obese (≥30.0)

Athlete C's BMI is approximately 28.68. This falls into the Overweight category.

1.1.4 Identify TWO athletes who may require further health advice. Provide ONE reason for the selected athletes.

• Athlete A: BMI $\approx 21.97$ (Normal)
• Athlete B: BMI $\approx 25.47$ (Overweight)
• Athlete C: BMI $\approx 28.68$ (Overweight)
• Athlete D: BMI $\approx 20.31$ (Normal)

The two athletes who may require further health advice are Athlete B and Athlete C.
Reason: Their BMI values fall into the Overweight category, which indicates a higher risk of certain health issues and may impact their athletic performance.
