The importance of including the unit of measurement:

12" x 12" = 1 sq ft

12' x 12' = 144 sq ft

12 m x 12 m = 1,550 sq ft

12 mm x 12 mm = 0.00155 sq ft

12 km x 12 km = 1,550,003,100 sq ft

One square in roofing is a 10 x 10 foot section or 100 square feet. 12 square would be 1,200 square feet of roof. 12 x 12 square would be 14,400 square feet of roof.

Then again, 12 squared = 144 regardless of unit and 12 times 12 squared would be 1,728.
