how many 300x300 mm tiles in a square metre
279 sq ft = 25.92 sq metres so, at 0.36 sq metres apiece, 72 slabs. This assumes that all offcuts can be used - a totally unrealistic assumption in real life.

The answer will depend on the size of the patio slabs.
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre

4.9382716 to be precise, so 5, 450x450 slabs in a square metre.
how many 300x300 mm tiles in a square metre
4.94, approx.
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.

You will need a minimum of 153 slabs. However, that answer assumes that the area to be covered is "well behaved" and that you are happy to use offcuts and chippings so that part of the area will look like a mosaic. If these conditions are not met, you should consider getting 5% extra slabs.If, for example, the 55 sq metre area is in the form of a rectangle which is 550 mm wide and 100 metres long it may be easier to cover it using 167 trimmed slabs in a long line rather than use offcuts which are 5 mm wide.
Depends on the linear dimensions of both the slabs and the ground.
