Find the perimeters of :
A square having each side of length 4.5 cm.

Answer

To find the perimeter of a square with each side measuring 4.5 cm, follow these steps:

### Step-by-Step Solution:

1. **Identify the formula for the perimeter of a square**:
The perimeter (P) of a square can be calculated using the formula:
\[ P = 4 \times \text{side} \]

2. **Substitute the given side length into the formula**:
Here, the length of each side of the square is given as 4.5 cm. So, we substitute this value into the formula:
\[ P = 4 \times 4.5 \, \text{cm} \]

3. **Perform the multiplication**:
Now, calculate the value:
\[ P = 4 \times 4.5 = 18 \, \text{cm} \]

4. **State the final answer**:
Therefore, the perimeter of the square is:
\[ P = 18 \, \text{cm} \]

### Final Answer:
The perimeter of the square is 18 cm.
