Concept Extensions

Body surface area (BSA) is often used to calculate dosages for some drugs. BSA is calculated in square meters using a
person’s weight and height.

1weight in kg2 * 1height in cm2

BSA =
C 3600

For Exercises 57 through 62, calculate the BSA for each person. Round to the nearest hundredth.You will need to use the
square root key on your calculator.
