URGENT> can someone please help as I'm about to finalise a property today. If the landlord provides the dimensions for a room, it is taken as the outside external walls or inside floor area?

I can't seem to find this info anyway on google. In certain countries, it's very clear if it's supposed to include window bays, your share of common hallways etc. Singapore??? Can any estate agent please confirm, especially as I'm being charge by the square foot.
Many thanks, anyone!
