Find the perimeter of a rectangle whose length and breadth are `"15.4 cm"` and `"11.6 cm"` respectively.

Options

A. `"45cm"`
B. `"108cm"`
C. `"54cm"`
D. `"52cm"`

Answer

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

### Step 1: Identify the length and breadth of the rectangle.
- The length (l) of the rectangle is given as 15.4 cm.
- The breadth (b) of the rectangle is given as 11.6 cm.

### Step 2: Use the formula for the perimeter of a rectangle.
- The formula for the perimeter (P) of a rectangle is:
\[ P = 2 \times (l + b) \]

### Step 3: Substitute the values of length and breadth into the formula.
- Substitute l = 15.4 cm and b = 11.6 cm into the formula:
\[ P = 2 \times (15.4 + 11.6) \]

### Step 4: Calculate the sum of length and breadth.
- Calculate \( 15.4 + 11.6 \):
\[ 15.4 + 11.6 = 27.0 \]

### Step 5: Multiply the sum by 2 to find the perimeter.
- Now, multiply the sum by 2:
\[ P = 2 \times 27.0 = 54.0 \text{ cm} \]

### Final Answer:
- The perimeter of the rectangle is **54.0 cm**.
