You can calculate the area and perimeter of a polygon based on a series of points you specify or enclose with a circle or closed polyline. You can also determine the area of several combined entities and add or subtract the area of one or more entities from a total combined area.
You can find the area and perimeter of any closed region by specifying a series of points. The program calculates the area and perimeter of the space that is enclosed by an imaginary polygon consisting of straight-line segments connecting each point.
As you select each successive point, the resulting polygon is displayed on the screen.
The area and perimeter of the region you defined are displayed. For example, the following type of information is displayed:
Area = 11.0583, Perimeter = 15.3092
Select the points (A, B, C) that form a polygon. The area and perimeter of the region are then calculated.
