Muita gente tenta resolver esse problema usando contas complicadas… mas a geometria permite encontrar a área quase de imediato. A figura pode ser interpretada como um retângulo de base 4 e altura total 8 (2 + 6). A área desse retângulo é 4 × 8 = 32 unidades de área. A região hachurada pode ser encontrada subtraindo três triângulos que não pertencem à área pedida. O triângulo superior tem base 3 e altura 2, então sua área é (3 × 2)/2 = 3. O triângulo inferior tem base 4 e altura 6, então sua
