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.
600 x 600 is 360,000.
Length x width x depth.
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
600 = 100% 180 = X% X = (180x100) ÷ 600 X = 30%

A square slab measuring 0.6 metres all round has an area of 0.36 square metres. This means that to cover an area of 24 square metres you will need 66 slabs and 2/3 of a slab. Covering the area may be problematic if 1/3 of a slab and 2/3 of a slab become involved, of lesser fractions, depending on the exact length and width which gave the area of 24 - and if there is a pattern to maintain.
100 centimeters per meter, so 100cm x 6 = 600 cm.

2.5% of 600 = 2.5% x 600 =2.5/100 x 600 (% means out of 100) = 2.5 x 6 =15
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
600 = 100% 180 = X% X = (180x100) ÷ 600 X = 30%
600 x 0.833... = 600 x 1/12 = 50

19.5 of 600 = 19.5 x 600 = 11,700 19.5 off of 600 = 600 - 19.5 = 580.5 19.5% of 600 = 600 x 0.195 = 117 19.5% off of 600 = 600 x 0.805 = 483
