Question 1124492

Use a model for body surface area, BSA, such that 
BSA = sqrt (wh/3600) , where  w = weight in kg and h = height in cm.
 
Find the weight of a 179-cm male to the nearest kg whose 
BSA = 2.3.
<pre>{{{matrix(1,3, BSA, "=", sqrt(wh/"3,600"))}}} 
{{{matrix(1,3, 2.3, "=", sqrt(179w/"3,600"))}}} -------- Substituting 2.3 for BSA, and 179 for h
{{{matrix(1,3, 2.3, "=", sqrt(179w)/sqrt("3,600"))}}}
{{{matrix(1,3, 2.3, "=", sqrt(179w)/60)}}}
{{{matrix(1,3, sqrt(179w), "=", 2.3(60))}}} ----- Cross-multiplying
{{{matrix(1,3, 179w, "=", (2.3(60))^2)}}} ---- Squaring both sides
{{{highlight_green(matrix(1,10, "w,", or, weight, "=", (2.3(60))^2/179, "=", "106.3911,", or, 106, kg))}}}
