Thus, the text adapts to changes of the object (e.g. new coordinates, area).[br][br][table][tr][td]1.[/td][td][icon]https://www.geogebra.org/images/ggb/toolbar/mode_text.png[/icon][/td][td]Select the [i]Text [/i]tool and click in the  [img]https://wiki.geogebra.org/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i].[/td][/tr][tr][td]2.[/td][td][/td][td]Enter [code]area =[/code] into the text field.[br][b]Hint:[/b] This will be the static part of your text.[/td][/tr][tr][td]3.[/td][td][/td][td]Click on [i]Advanced[/i] and select tab [img]https://wiki.geogebra.org/uploads/thumb/4/4e/Geogebra-logo-elipse.svg/16px-Geogebra-logo-elipse.svg.png[/img] [i]Objects[/i].
