A room that measures 12 x 12 is 144 sq ft.
Answer: 144 ft² = 13.3780 m²
Oh, dude, you're really getting into the nitty-gritty here. So, technically, there are about 907 steel bars in one ton of 12mm diameter bars that are 12 meters long. But like, who's really counting, right? Just throw 'em in there and call it a day.
Assuming the room measures 12 feet by 7 feet - and there is absolutely no reason to make that assumption as against 12 cubits x 7 cubits - the area is 12*7 = 84 square feet.
None, since there are no such measures as millameters nor centameters. However, 12 millimetres equals 1.2 centimetres.
