Convert athlete heights to meters, calculate their BMIs, and classify Athlete C's BMI.

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

1.1.2 Calculate the BMI of each athlete using the formula below.

• Athlete A: $$\text{BMI}_A = \frac{62 \text{ kg}}{(1.68 \text{ m})^2} = \frac{62}{2.8224} \approx 21.96$$
• 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.

Athlete C's BMI is approximately 28.68.
According to the chart:

• Underweight (<18.5)
• Normal (18.5–24.9)
• Overweight (25.0–29.9)
• Obese (≥30.0)

Since $25.0 \le 28.68 \le 29.9$, Athlete C is classified as Overweight.

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

• Athlete A: BMI 21.96 (Normal)
• Athlete B: BMI 25.47 (Overweight)
• Athlete C: BMI 28.68 (Overweight)
• Athlete D: BMI 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 they are at an increased risk for certain health conditions.
