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 =

Body surface area B = SQRT(hw/60)

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

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)
