Step-by-step Solution
Claro, aquí tienes la información en español:
### a. Diagrama del tapete del dormitorio de Nathan
Imaginemos que el tapete del dormitorio tiene un lado más largo de 5 pies. Dado que el área del tapete es de 15 pies cuadrados, podemos calcular el lado más corto.
\[
\text{Área} = \text{largo} \times \text{ancho}
\]
\[
15 = 5 \times \text{ancho}
\]
\[
\text{ancho} = \frac{15}{5} = 3 \text{ pies}
\]
Entonces, el tapete del dormitorio mide 5 pies de largo y 3 pies de ancho.
**Diagrama:**
```
+-------------------+
| |
| | 3 pies
| |
+-------------------+
5 pies
```
### b. Diagrama del tapete de la sala de estar de Nathan
El tapete de la sala de estar es el doble de largo y el doble de ancho que el tapete del dormitorio.
- Largo del tapete de la sala de estar: \(2 \times 5 = 10\) pies
- Ancho del tapete de la sala de estar: \(2 \times 3 = 6\) pies
**Diagrama:**
```
+-------------------------+
| |
| | 6 pies
| |
+-------------------------+
10 pies
```
### Cálculo del perímetro del tapete de la sala de estar
El perímetro se calcula con la fórmula:
\[
\text{Perímetro} = 2 \times (\text{largo} + \text{ancho})
\]
\[
\text{Perímetro} = 2 \times (10 + 6) = 2 \times 16 = 32 \text{ pies}
\]
Por lo tanto, el perímetro del tapete de la sala de estar es de **32 pies**.
Quick Answer
El perímetro del tapete de la sala de estar es de 32 pies.
