In the United States, an over-weight person is defined as anyone with a body mass index or BMI of 27.6 or higher. The World Health Organisation defines an overweight person as one with a BMI of 25 or higher.

Calculate the BMI rounded to the nearest tenth for each of these people: a. 5ft 5 in., 165 lb b. 6ft, 185 lb c.
