A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is
Area =
Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area. Here is a sample run:
Homework Answers
Program Plan:
• Define the class testArea.
• Define the main() method.

A regular n-gon is a polygon with n sides of equal length, in which all angles are equal. Join every pair of vertices by a chord, and let f(n) be the number of pairs of chords that cross each other; so for example f(3) = 0, f(4) 1, and f(5) = 5. Find a formula for f(n).

Write a program that displays a convex regular polygon with m or n sides, where m is the last digit of your student number plus 3, n is the second last digit plus 3. Use two buttons named “before” and “after” to change the number of sides of the polygon. Click on “before” button will show a convex regular polygon with m sides and click on “after” will show a convex regular polygon with n sides. For example, a student...
