How to Calculate the Area of a Square
Understanding the Square
- A square is defined as a flat figure with four equal sides that are parallel and four equal angles, making it a regular polygon.
- The area of a square is measured in square centimeters, square meters, or square kilometers. It represents the number of square units contained within the figure.
Formula for Area Calculation
- The formula to calculate the area of a square is: Area = side × side.
- For example, if each side of a square measures 3 centimeters, then its area is calculated as 3 × 3 = 9 cm².
Practical Examples
- An example involves Patricia building her house on a square plot where each side measures 20 meters. To find the total area, we multiply: 20 × 20 = 400 m².
- This means Patricia's house will have an area equivalent to 400 one-square-meter squares.
Additional Example: Garden Area
- Patricia also plans to build a garden in the shape of another square with each side measuring 8 meters.
- The area calculation for this garden would be: 8 × 8 = 64 m², indicating that it will cover an area of 64 square meters.
