The rule of nines is used for quick estimation of burn surface area in adults. According to this rule, the entire head and neck account for 9%, each arm for 9%, each leg for 18%, the anterior trunk for 18%, the posterior trunk for 18%, and the genital area for 1%. In this case, the front torso (18%) and the front of the right arm (4.5%, half of 9% since only the front is mentioned) are involved, totaling 22.5%.
