Muita gente tenta resolver esse exercício usando fórmulas complicadas… mas aqui a lógica resolve tudo em segundos. Observe a figura inteira como se fosse um grande retângulo de 4 m por 6 m. A área desse retângulo completo seria: 4 × 6 = 24 m² Só que a figura em “L” possui área de apenas 16 m². Então existe uma parte “faltando” nesse retângulo maior: 24 − 16 = 8 m² Essa região faltante é exatamente o retângulo que envolveria o triângulo azul. E aqui vem o detalhe mais elegante: o triângulo o
