The perimeter of a rectangle with length l and breadth b is _______ .

Options

A. `2(l xx b)`
B. `2(l-b)`
C. `2(l+b)`
D. `l+b`

Answer

To find the perimeter of a rectangle with length \( l \) and breadth \( b \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Rectangle**: A rectangle has two lengths and two breadths. The opposite sides of a rectangle are equal.

2. **Identify the Formula for Perimeter**: The perimeter \( P \) of a rectangle can be calculated using the formula:
\[ P = 2 \times (l + b) \]

3. **Substitute the Values**: In this case, we will substitute \( l \) for length and \( b \) for breadth into the formula:
\[ P = 2 \times (l + b) \]

4. **Simplify the Expression**: This can be simplified to:
\[ P = 2l + 2b \]

5. **Final Result**: Therefore, the perimeter of the rectangle is:
\[ P = 2(l + b) \]

### Final Answer:
The perimeter of a rectangle with length \( l \) and breadth \( b \) is \( 2(l + b) \).
