To calculate the Body Mass Index (BMI), we use the formula:
ext{BMI} = rac{ ext{weight (kg)}}{ ext{height (m)}^2}
Given that the person's height is 170 cm, we convert it to meters:
ext{height} = rac{170}{100} = 1.7 ext{ m}
Now, substituting the values into the BMI formula:
ext{BMI} = rac{70}{(1.7)^2} = rac{70}{2.89} \\ ext{BMI} \\ ext{approximately equals} \\ 24.2Select the correct option
