Jill is considered overweight. To calculate BMI, we must divide weight in pounds by height (in inches)^2 and then multiply by a factor of 703 (because we are doing the calculation in English units). Jill is 5 feet 6 inches tall, which is equivalent to 66 inches. [175 / (66 ^2)] * 703 = 28.24. BMI between 25 and 29.9 is considered overweight.
