Study Notes
- 2-dimensional shapes have a 1-dimensional quantity called Perimeter and a 2-dimensional quantity called Area.
- Area is the space or surface covered by moving a 1-dimensional line in a perpendicular direction.
- Area units are important when measuring area (e.g., square centimeters, square meters, square miles).
- The formula for squares and rectangles area is Area = length x width, written as A = L x W.
- Units like cm², in², or m² indicate measurements of 2-dimensional quantity area.
- The formula for triangles' area is Area = 0.5 x base x height, where base and height are chosen based on the triangle's orientation.
- The formula for triangles works for all triangle types (acute, obtuse, right) by calculating one-half of the base times height.
- Practice problems are essential for mastering the calculation of area for various shapes.
