write notes of all the relevant information (no need to turn those notes in). The reading questions below are meant to help
you.
Reading
Questions:
1. Learn or remind yourself of the
following: region, area, unit square, square unit, composite regions, unit of area, union, intersection, and perimeter.

of a rectangle is length times width. How is this different for rectangles with
lengths that are whole numbers versus real number side lengths?
3. How are the area and perimeter of
an object related?
4. What is the difference between a
unit square and a square unit?
5. What can be misleading about the

triangle.
6. Explain the two different
approaches (section 5.3) for proving the area formulas for triangles and
parallelograms.
