Is there a way to tell how long a line is?

I need to be able to tell how long a line or group or lines are. So if I drew a 2 inch square box I would like to be able to see that the total length of the line is 8 inches. The actual lines I will need to know the length of will not be straight and uniform, they will be curved and jagged and there will be multiple lines so it would be nice to select them all and see that is have 45 inches of line or whatever it may come out to. Is this possible? My actual application for this is estimating cutting time on my laser. If I know the total line length I can estimate the time it will take to cut the piece. Thanks Greg
