Find the area and the perimeter of a square each of whose sides is 6.3 cm long.

Answer

To find the area and the perimeter of a square with each side measuring 6.3 cm, we can follow these steps:

### Step 1: Calculate the Area of the Square
The formula for the area \( A \) of a square is given by:
\[ A = \text{side}^2 \]
Here, the length of each side is 6.3 cm. Therefore, we can substitute this value into the formula:
\[ A = (6.3 \, \text{cm})^2 \]

### Step 2: Perform the Calculation for Area
Now, we need to calculate \( 6.3 \times 6.3 \):
\[ A = 6.3 \times 6.3 = 39.69 \, \text{cm}^2 \]

### Step 3: Calculate the Perimeter of the Square
The formula for the perimeter \( P \) of a square is given by:
\[ P = 4 \times \text{side} \]
Substituting the side length into the formula:
\[ P = 4 \times 6.3 \, \text{cm} \]

### Step 4: Perform the Calculation for Perimeter
Now, we calculate \( 4 \times 6.3 \):
\[ P = 4 \times 6.3 = 25.2 \, \text{cm} \]

### Final Results
- **Area of the square**: \( 39.69 \, \text{cm}^2 \)
- **Perimeter of the square**: \( 25.2 \, \text{cm} \)
