These are student samples of some of the things we are learning about area (Length x Width, or the number of tiles) and perimeter (2Length + 2Width). We have learned (and their examples will show) learned that you can have an unchanging perimeter and a changing area OR you can have an unchanging area and a changing perimeter.
The first four examples show an unchanging area of 6 square units and changing perimeters.
The first four examples show an unchanging area of 6 square units and changing perimeters.
The following four examples show a fixed area of 24 square units and changing perimeters.
