Study Notes
Rectangle Perimeter
- Perimeter of a rectangle is calculated by adding together the lengths of all sides.
- Formula: Perimeter = 2(length + width).
- Standard units for measurement include centimeters (cm), meters (m), inches (in), and feet (ft).
Area of Shapes
- Area measures the space inside a shape, using square units.
- For a rectangle, Area = length × width; measured in square centimeters (cm²), square meters (m²), square inches (in²), or square feet (ft²).
- Other shapes have specific formulas for area:
- Circle: Area = π × radius².
- Triangle: Area = (base × height) / 2.
Time Measurement
- Time is measured using standard units such as seconds, minutes, and hours.
- It is essential to convert between different units to maintain consistency in measurement.
- Measuring time accurately often involves rounding to the nearest tenth for precision.
Object Attributes
- Attributes of objects may include length, width, height, volume, and weight.
- Choosing appropriate units for measurement depends on the context, such as using grams for weight or liters for volume.
- Use tools like rulers or measuring tapes for length, scales for weight, and graduated cylinders for volume.
