Step-by-step Solution

Para determinar as dimensões do retângulo \(ABCD\), podemos usar a fórmula do perímetro de um retângulo, que é dada por: \[ P = 2 \times (l + w) \] Onde: - \( P \) é o perímetro do retângulo, - \( l \) é a medida da base do retângulo, e - \( w \) é a medida da altura do retângulo. Dado que o perímetro do retângulo é \(28 \, \text{cm}\) e a medida da base \(AB\) é \(6 \, \text{cm}\), podemos substituir esses valores na fórmula do perímetro e resolver para encontrar a medida da altura \(w\). Vamos calcular a medida da altura \(w\). Solve the equation by following steps: - step0: Solve for \(w\): \(2\left(6+w\right)=28\) - step1: Divide both sides: \(\frac{2\left(6+w\right)}{2}=\frac{28}{2}\) - step2: Divide the numbers: \(6+w=14\) - step3: Move the constant to the right side: \(w=14-6\) - step4: Subtract the numbers: \(w=8\) A medida da altura do retângulo \(ABCD\) é \(8 \, \text{cm}\). Portanto, as dimensões do retângulo são \(AB = 6 \, \text{cm}\) e \(AD = 8 \, \text{cm}\).

Quick Answer

As dimensões do retângulo \(ABCD\) são \(AB = 6 \, \text{cm}\) e \(AD = 8 \, \text{cm}\).
