I am not sure if you want to measure distances (length) or and area. In either case, you can use the measuring tool found in the tool bar. You may need to activate this particular tool in the GUI. The other option is to use the actuelle lines that you have and extract the length of the line using an expression.
Look for « expressions » on this page. If you want to measure an area, you can convert the lines you select into a polygon and use a expressing to extract the area of the polygon. Google « Line to polygon and QGIS » to find what you need.
