GST Applicability on renting stalls

I am having an Event Management Company. I have purchased canopy tents as assets for using it in expos, fairs and conventions. Now I am giving these tents on daily rental basis to the vendors to use in different type of events organised by my company. Whether I should charge GST on this income? If yes, how much should I charge and under which section? Further the stall numbers will be around 400 and the rental amount range per Tent will vary between 30,000 to Rs 49000.
