Introduction to Lesson: Relating Area and Perimeter

This lesson looks at how area and perimeter connect. It digs into changes in sides and the results. Each shift in length or width changes the space inside and the outline.

This lesson invites you to play experiments. Each task asks you to drag points or type numbers. A friendly voice explains each step. You watch the shape fill and its border shift.

A rectangle shows a set width and a set length. You stretch one side to see the space jump up. The border expands at its own rate. You spot how each measure moves on its own track.
