Use this applet to find the perimeter of a variety of shapes with the same or different areas.

In this activity, students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They then use the patterns and the calculator to predict the perimeter of a specific shape in the sequence.

Students use a graphing calculator to find maximum and minimum values for area and perimeter problems.

Practice using your graphing calculator for Geometry problems. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each problem.
