Understanding the Square
A square is a special type of quadrilateral where all four sides are equal in length, and all angles are right angles. In this case, the side length is given as 2.1 cm.
Calculating the Area
The area of a square can be calculated using the formula:
- Area = Side × Side
For our square:
- Area = 2.1 cm × 2.1 cm
This simplifies to:
- Area = 4.41 cm²
Thus, the area of the square is 4.41 cm².
Calculating the Perimeter
The perimeter of a square can be calculated using the formula:
- Perimeter = 4 × Side
Applying this to our square:
- Perimeter = 4 × 2.1 cm
This simplifies to:
- Perimeter = 8.4 cm
Therefore, the perimeter of the square is 8.4 cm.
Summary of Results
- Area: 4.41 cm²
- Perimeter: 8.4 cm
Understanding these fundamental properties of a square not only aids in geometry but also enhances spatial awareness in real-world applications.
