Approximately $1.69$ square meters.
Work Step by Step
Given formula: $B=\sqrt\frac{hw}{3131}$, where $B$ is an individual’s body surface area in square meters, $h$ is the individual’s height in inches, and $w$ is the individual’s weight in pounds.
Substitute values from the question into the formula.
$B = \sqrt \frac{66\times135}{3131}$
$B = \sqrt\frac{8910}{3131}$
$B\approx1.69$
The individual's body surface area is approximately $1.69$ square meters.
