To calculate the Body Mass Index (BMI), you can use the following formula:
\[ \text{BMI} = \frac{\text{weight in kilograms}}{(\text{height in meters})^2} \]
First, let's convert Mari's height from centimeters to meters.
- Height: 163 cm = 1.63 m
- Weight: 25 kg
Now, applying the BMI formula:
\[ \text{BMI} = \frac{25 \text{ kg}}{(1.63 \text{ m})^2} \]
Calculating \( (1.63 \text{ m})^2 \):
\[ (1.63)^2 = 2.6569 \]
Now, calculate the BMI:
\[ \text{BMI} = \frac{25}{2.6569} \approx 9.42 \]
So, Mari's BMI is approximately 9.42. This value is considered significantly below the normal weight range, which suggests that it might be important to consult with a healthcare professional for further evaluation.
