Determine Jonathan's weight status based on his body mass index (BMI).

Jonathan has a mass of 85 kg and a height of 176 cm.

Answer :

We start by converting the height from centimeters to meters. Given that Jonathan's height is 176 cm, we have:

$$
1.76 \text{ m} = \frac{176 \text{ cm}}{100}
$$

Next, we use the Body Mass Index (BMI) formula:

$$
\text{BMI} = \frac{\text{mass}}{\text{height}^2}
$$

Substituting the values (mass = 85 kg and height = 1.76 m):

$$
\text{BMI} = \frac{85}{(1.76)^2} \approx 27.44
$$

The BMI classification is typically as follows:
- Underweight: BMI $< 18.5$
- Normal weight: $18.5 \leq \text{BMI} < 25$
- Overweight: $25 \leq \text{BMI} < 30$
- Obese: $\text{BMI} \geq 30$

Since Jonathan's BMI is approximately $27.44$, which falls in the range of $25$ to $30$, his weight status is classified as:

$$
\text{Overweight}
$$
