Sagot :
Step-by-step explanation:
To solve this problem, we need to determine the perimeter and area of a rectangle, given its length and width.
Given:
- Length (\( l \)) = 18 cm
- Width (\( w \)) = 6 cm
### Area of the Rectangle
The area (\( A \)) of a rectangle is calculated using the formula:
\[ A = l \times w \]
Substituting the given values:
\[ A = 18 \, \text{cm} \times 6 \, \text{cm} \]
\[ A = 108 \, \text{cm}^2 \]
### Perimeter of the Rectangle
The perimeter (\( P \)) of a rectangle is calculated using the formula:
\[ P = 2(l + w) \]
Substituting the given values:
\[ P = 2(18 \, \text{cm} + 6 \, \text{cm}) \]
\[ P = 2(24 \, \text{cm}) \]
\[ P = 48 \, \text{cm} \]
### Summary
- **Area:** \( 108 \, \text{cm}^2 \)
- **Perimeter:** \( 48 \, \text{cm} \)
