Best Answer

The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions.

21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs.

To complete the rectangular area, 14.2 x 12.9 = 183 slabs.
