Yeah it is correct. One thing which made me a bit of uncomfortable was the naming convention. Lo (L not), instead of Lp should be used. Also give the percentage at the end which tells you how much the length of a rod contracts in moving frame.
Before formula, you should also mention "Using Lorentz–FitzGerald contraction, the length observed in relative motion with the object is,".
These are just my views; you may disagree.
