Question

Macy is 15 years old and weighs 103 pounds. She is 61 inches tall and is average size

Answer 1

Answer:

19.46

Explanation:

BMI (body mass index) is a value derived from the mass and height of a person. It is used to determine whether a person has a healthy weight.

Usually, BMI is expressed in metric units - kg/m². You get it by simply dividing the person's weight in kilograms by their height in meters squared. When it comes to the imperial units used in the US, you should divide the weight in pounds by height in inches squared and then multiply that by 703. This means that the formula looks like this:

$BMI = \frac{m}{h^2} * 703$

This is how we'll get the result 19.46. People who have a BMI of 18.5–24.9 are considered to be of normal weight, which means that Macy is of average size for a teenager.
