To find the area of multiple objects in AutoCAD, you can use the AREA command. This command will allow you to select multiple objects and then calculate the total area of all the selected objects. To use this command, simply type AREA into the command line and then press Enter. This will bring up the Area dialog box. From here, you can select the objects that you want to include in your calculation. Once you have made your selections, simply click on the Calculate button and AutoCAD will provide you with the total area of all selected objects.
