Para calcular a área do retângulo, precisamos determinar sua largura, pois a altura já é conhecida e vale 11. Observando a figura, acima do retângulo há um triângulo retângulo cuja hipotenusa mede 13 e um dos catetos mede 12. Como o ângulo entre a base do triângulo e o lado vertical é de 90°, podemos aplicar o Teorema de Pitágoras para encontrar o outro cateto, que corresponde exatamente à largura do retângulo. Pelo Teorema de Pitágoras, o quadrado da hipotenusa é igual à soma dos quadrados dos
