Visual Proof of (a + b)² = a² + 2ab + b² Using Area Model #29463 (License: Personal Use)

This hand-drawn diagram represents the square of a binomial (a + b)² as a large square subdivided into four regions: two rectangles labeled ab, one square labeled a², and another labeled b². The visual reinforces that the total area equals a² + 2ab + b², offering an intuitive geometric interpretation of algebraic expansion. The rough, inked style suggests a classroom or textbook derivation.

Used in math education contexts-especially algebra lessons-to teach binomial expansion visually; matches user intent for understanding or teaching the (a + b)² identity through geometric reasoning.
