Body surface area is an important piece of medical information because it is a factor in temperature regulation as well as some drug level determinations. The Mosteller formula gives one way of estimating body surface area B in square meters. The formula uses the weight w in kilograms and the height h in centimeters. The relation is
B = 
hw
60
.
In this exercise we consider people who are 170 centimeters tall.
(a) Write a formula for B as a function of w
B =

Thank you for the opportunity to help you with your question!

Body surface area B = SQRT(hw/60)

Note:  Please read SQRT as 'square root of'

Which can also be re-written as (by squaring on both sides):   B^2 = hw/3600

Note:  Please read B^2 as B square

As height h is considered as 170 cm here in this exercise  B^2 = 170w/3600

Solving further gives:  B^2 = 17w/360

Applying square root on both sides and writing as function of w:   B(w) = SQRT(17w/360)


Please let me know if you need any clarification. I'm always happy to answer your questions.
