Explore the fundamental geometric shape of the rectangle, characterized by four right angles and congruent opposite sides. Understand how to construct a rectangle, calculate its area with the formula A = l × w, and determine its perimeter using P = 2(l + w). Distinguish between rectangles and squares, noting that squares have equilateral sides and perpendicular diagonals, while rectangles do not.
