What percent of body surface area is considered burned when both legs, the front torso, and the groin are affected?

To determine the percentage of body surface area considered burned when both legs, the front torso, and the groin are affected, we can refer to the "Rule of Nines," which is a method commonly used in emergency medicine to assess the total body surface area burned.

According to the Rule of Nines:

• Each leg accounts for 18% of total body surface area (9% for the front and 9% for the back).

• The front torso accounts for 18% of total body surface area.

• The groin area accounts for 1%.

When calculating the total for this scenario:

• Both legs contribute 36% (18% each for front and back).

• The front torso contributes another 18%.

• The groin adds an additional 1%.

When we sum these values, the total body surface area burned is:

36% (both legs) + 18% (front torso) + 1% (groin) = 55%.

Thus, the correct answer reflects the combined assessment of the affected areas based on this established medical guideline, which indicates that 55% of body surface area is considered burned in this scenario.
