If you want help quickly, you will need to explain where V is in relation to the rectangle STUW. All the distances are related to V. Is V in the rectangle or outside it, for example? This answer will then be replaced by the proper answer before midnight (which time zone?).
From the information you have given I estimate that ST=WU=19.36 approx (19.4 to the nearest tenth), but this may only be one solution and may not be unique. ST^2=SV^2-TV^2=400-25=375. ST=5√15=19.36=19.4 to nearest tenth.
The picture below shows examples of the layout that fit the criteria.
