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.
first lets convert m to mm.we know, 1 m=1000 mm. 5 m =5000 mm and 8m=8000mm. Now, no.of paving slab = area of flags /area of slab . =5000 X8000/450 x 450. =197.5 = 197 slabs.

400 at least
For blocks that are 450mm x 225mm , you will need 9.88 blocks per square metre.
You need only 8 and half sheets of slab.
It depends on the shape of the 40m2. If it is 1m x 40m then, despite the area being 40m2, there is not a single 450mm x 450mm in it. The shape is simply not wide enough. But if you're allowed to cut up the slabs to make them fit, then you need 198 of them in order to cover 40 m2 of area.

600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
450mm*450mm = 0.2025 sq metres. Area to be covered = 1 square metre So number of flags required = 1/0.2025 = 4.9, or 5. However, 5 will leave the area looking like a mosaic.
It requires 183 450x450mm tiles to cover 37 square meters of area. However this does not take into account waste. For laying ceramic tile on concrete the rule of thumb is to assume about 10% extra for waste, so you would need about 200 tiles.
If most of the off-cuts are also used then you will need 315 slabs. Otherwise you will need a lot more.

Depends on the linear dimensions of both the slabs and the ground.
Joe needs 460 paving slabs to surrond the pond.
You will need 63 44cm x 44cm slabs to cover that area.
