Study Notes
Parallelogram Area Calculations
- Parallelogram area calculation formula: Area = base × height
- Ensure height is perpendicular to the base
- Units are crucial; ensure consistency (e.g., cm, m)
- Example: If base = 7 cm and height = 3 cm, then Area = 7 cm × 3 cm = 21 cm².
Parallelogram Properties and Area
- Opposite sides are parallel and equal in length
- Opposite angles are equal
- Diagonals bisect each other
- Area = base × height
- Different methods to find the height (perpendicular distance between two parallel lines)
- Using given values to calculate unknown sides/height
- Illustrative examples (diagrams, figures, and values) are vital for understanding.
