A person has a mass of 84 kg and is 2 m tall.

Use the equation [tex]$BMI=\frac{\text {mass}}{\text {height}^2}$[/tex] to calculate their BMI.

Answer :

To calculate the Body Mass Index (BMI), you can use the formula:

[tex]\[ \text{BMI} = \frac{\text{mass}}{\text{height}^2} \][/tex]

Let's go through the steps to find the BMI for a person with a mass of 84 kg and a height of 2 meters:

1. Identify the measurements:
- Mass = 84 kg
- Height = 2 m

2. Use the BMI formula:
Substitute the values into the formula:

[tex]\[
\text{BMI} = \frac{84}{2^2}
\][/tex]

3. Calculate the height squared:
[tex]\[
2^2 = 4
\][/tex]

4. Divide the mass by the height squared:
[tex]\[
\text{BMI} = \frac{84}{4} = 21.0
\][/tex]

The BMI for this person is 21.0.
