Algebra Tiles Area and Perimeter

Mr. Dell explains how to calculate the area and perimeter of shapes using algebra tiles. He describes the different types of tiles, including x squared, x, and unit tiles, and demonstrates how to simplify expressions for area and perimeter. The video also discusses how rearranging the tiles affects the area and perimeter, concluding that the area remains constant while the perimeter may change.
