Question

The Mosteller formula for approximating the surface area S, in square meters (m²), of a humanis given by the function below, where h is the person's height in centimeters and wis the person's weight in kilograms. According to this formula, ifa person's weight drops 20%, by what percentage does his or her surface area change?VhwS(h.w) -60Retblese aChoose the correct answer below.munic O A. It drops by approximately 10%.B. It drops by approximately 30%OC. It drops by approximately 20%.OD. It drops by approximately 40%.

Answer 1

Given the parameter in the question, we were asked to determine by what percentage does his or her surface area change.

Recall that:

Since surface area is a product of height and weight, a percentage of decrease in any of the parameter will give an equivalent percentage decrease.

From what is explained above, there will be approximately 20% drop.

The correct option is C, which is Drops by approximately 20%.
