Answer

2.31 square meters

Work Step by Step

Given: $B=\sqrt{\dfrac{hw}{3131}}$ where $B$ is an individual's body surface in square meters, $h$ is the individual's height in inches, and $w$ is the individual's weight in pounds. Individual is 74 inches tall and weighs 225 pounds. Find the body surface area. Plug in given information and solve: $B=\sqrt{\dfrac{(74)(225)}{3131}}$ $B=\sqrt{\dfrac{16650}{3131}}$ $B=2.306033357$ Round answer to two decimal places and add units: The body surface area of the individual is 2.31 square meters.
