This lesson assumes that the student has some familiarity with calculating areas, perimeters and circumferences.  

The main purpose of the lesson is to focus on problem solving skills.  This is done by presenting non-standard regions which require the learner to develop strategies for breaking a problem into smaller more manageable "chunks".
