Unformatted text preview: WORKSHEET 26  Fall 1995 1. What is area? a) List the geometric objects for which you know how to find the area. Include the formula you would use (and, of course, the meaning of any variables used.) How do you know these formulas? b) Describe some geometric objects for which you cannot find the area. c) Given any set in the plane (a rectangle or circle or blob) you have a concept of the area of that set. Describe this general concept of area as a function A . That is, A will have a domain and range. Specify whay they are. (Hint: Unlike most functions you have considered, the domain of A is NOT any set of numbers!) d) What are some properties that the function A should have. Here is some terminology which may be helpful: Subset: A B means A is contained in B . Intersection: C = A B means C is the set of points that are in both A and B . Union: D = A B means D is the set of points that are in either A or B ....
