Perimeter and Area with Algebra Tiles

This GeoGebra example demonstrates how algebraic expressions relate to the perimeter and area of geometric shapes using algebra tiles. It visually shows how variables like x represent side lengths, and how polynomial expressions for perimeter and area can be built from tile arrangements. Core concepts include polynomial expressions, area formulas, perimeter calculations, and the connection between algebra and geometry. The construction uses the command PosXSquared to create x² tiles, along with objects A, q1, functions f, g, h, i, and text objects text1 and text2 to display results. Suitable for middle school to high school students learning introductory algebra or geometry, and useful for teachers to illustrate the meaning of algebraic terms in a concrete, visual way.
