Question

1. what are the bmi and weight status of a person who is 5 feet tall and weighs 160 pounds? (see example 4 in section 1 - 2.)

Explanation:

Step1: Convert height to inches

Since 1 foot = 12 inches, a person 5 feet tall is $5\times12 = 60$ inches.

Step2: Convert height to meters

1 inch = 0.0254 meters, so 60 inches is $60\times0.0254= 1.524$ meters.

Step3: Convert weight to kilograms

1 pound = 0.453592 kilograms, so 160 pounds is $160\times0.453592 = 72.57472$ kilograms.

Step4: Calculate BMI

The formula for BMI is $BMI=\frac{weight(kg)}{height(m)^2}$. Substituting the values, we have $BMI=\frac{72.57472}{1.524^2}=\frac{72.57472}{2.322576}\approx31.3$.

Step5: Determine weight - status

A BMI of 31.3 falls into the "obese" category (BMI ≥ 30 is considered obese).

Answer:

BMI is approximately 31.3 and the weight - status is obese.
