Well, isn't that a happy little question! To cover 37 square meters with 450mm x 450mm paving slabs, you would need approximately 925 slabs. It's like painting a beautiful landscape, each slab fitting perfectly to create a lovely, harmonious surface. Just remember to take your time and enjoy the process!

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.
Depends on the linear dimensions of both the slabs and the ground.
You would need a total of 160
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 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.
1 slab of 1200 metres x 450 metres will certainly cover 1600 square metres. You may have trouble moving it into position, though.
