Subject: Calculating areas defined by points

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.

To calculate the area defined by points you specify

   1   Do one of the following to choose Area ():

   On the ribbon, choose Tools > Area (in Inquiry).

   On the menu, choose Tools > Inquiry > Area.

   On the Inquiry toolbar, click the Area tool.

   Type area and then press Enter.

   2   Specify the first point.

   3   Specify the second point.

   4   Continue specifying points in sequence to define the perimeter of the area you want to measure.

As you select each successive point, the resulting polygon is displayed on the screen.

   5   To complete the calculation, press Enter.

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.
