## Area of Quadrilaterals

Summary

The content provides a comprehensive guide on calculating the areas of special quadrilaterals, emphasizing the importance of understanding the base and height relationship, and the application of the Pythagorean theorem for irregular shapes.

- The area of a square is calculated as the side length squared, highlighting the geometric origin of algebraic squaring.
- For rectangles, rhombuses, and parallelograms, the area formula is base times height, with the height being perpendicular to the base.
- The Pythagorean theorem is crucial for finding the height in rhombuses and parallelograms when it is not directly given.
- Trapezoids require averaging the lengths of the two bases and multiplying by the height for the area calculation.
- Subdividing irregular quadrilaterals into rectangles and right triangles can simplify the process of finding their areas.
