The answer will depend on the size of the patio slabs.
400 at least
23.41 sq m

20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs

20 I believe
To calculate how many 400mm x 400mm paving slabs fit in one square meter, first convert the dimensions of the slab to meters: 0.4m x 0.4m. The area of one slab is 0.16 square meters (0.4m x 0.4m). Therefore, to find how many slabs fit in one square meter, divide 1 square meter by the area of one slab: 1 / 0.16 = 6.25. Since you can’t have a fraction of a slab, you can fit 6 slabs in one square meter, with some leftover space.

20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
You will need 63 44cm x 44cm slabs to cover that area.
40 slabs
220 should do it.
42 slabs...
