Find the perimeter of a rectangle whose length is 9 cm and breadth is 6 cm.

Answer

To find the perimeter of a rectangle, we can follow these steps:

### Step 1: Understand the formula for the perimeter of a rectangle.
The formula for the perimeter (P) of a rectangle is given by:
\[ P = 2 \times ( \text{Length} + \text{Breadth} ) \]

### Step 2: Identify the length and breadth of the rectangle.
From the question, we have:
- Length (L) = 9 cm
- Breadth (B) = 6 cm

### Step 3: Substitute the values into the formula.
Now, we can substitute the values of length and breadth into the perimeter formula:
\[ P = 2 \times (9 \, \text{cm} + 6 \, \text{cm}) \]

### Step 4: Calculate the sum of length and breadth.
First, calculate the sum inside the parentheses:
\[ 9 \, \text{cm} + 6 \, \text{cm} = 15 \, \text{cm} \]

### Step 5: Multiply the sum by 2.
Now, multiply the sum by 2 to find the perimeter:
\[ P = 2 \times 15 \, \text{cm} = 30 \, \text{cm} \]

### Step 6: State the final answer.
Thus, the perimeter of the rectangle is:
\[ \text{Perimeter} = 30 \, \text{cm} \]
