In adults, what percent of total body surface area does each leg (including both front and back) represent?

Explanation:
In adults, burn area is estimated using the Rule of Nines. Each leg, including both front and back surfaces, accounts for about 18% of total body surface area. This comes from 9% for the anterior leg plus 9% for the posterior leg, summing to 18%. The other options don’t fit this distribution: 9% would correspond to just one surface or a smaller region, 36% would be the total for both legs, and 13.5% isn’t a standard adult TBSA estimate.
