Hi @autocad1878,
Have you figured out how to calculate the area in AutoCAD LT? It looks like @h_s_walker has given you some great help.
If you have a closed polyline you can simply select it and it will show the area in the Properties palette. If you have a bunch of lines you can edit them using PEDIT to make them a closed polyline or you can also use BO (Boundary) to drop in a polyline.
If the display of the area is in MM and you want Meters, an easy way to get this to display is with a Field.
I made a quick video of that process for you.
I hope this helps.
