Solve the problem.When determining appropriate doses of medication, it is sometimes important to estimate the body surface area (BSA) of a patient. This surface area (in m2) can be approximated using the Mosteller formula BSA = 
1/2, where h is the patient's height in centimeters and w is the weight in kilograms. Determine the BSA for a patient with height 188 cm and weight 91 kg. Round your answer to two decimal places.
A. 22.58 m2 B. 4.75 m2 C. 0.04 m2 D. 2.18 m2
