To determine if a 12-year-old is overweight, we need to calculate their Body Mass Index (BMI). First, convert height to inches (64 inches). Next, calculate BMI using the formula: weight (lbs) / height (in) squared x 703. In this case, BMI = 115 / (64^2) x 703 ≈ 19.7. A BMI between 18.5-24.9 is considered healthy, so a BMI of 19.7 indicates this individual is not overweight.
