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.
Convert the 'mm' to 'm'
450 mm = 0.45 m
0.45 m X 0.45 m = 0.2025 m^2
40 m^2 / 0.2025 m^2 = 197.53
So you will need at least 198 tiles.

How many slabs would you need for a square meter if flags are 450mm x 450 mm?
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.

How many 450mm x 450mm paving slabs to cover 37 square mtrs?
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.

What is the area of a circle where the diameter measures 450mm?
The formula to find the area of a circle is A = πr2, where A is area, π is pi (3.14159), and r is the radius. The radius is half the diameter, 1/2d or d/2. r = d/2 = 450mm/2 = 225mm A = πr2 = 3.14159 x (225mm)2 = 15904mm2
How many 450mm x 450mm slabs will cover the space of 20ft x 20ft?
20 ft= 6096 mm (6096 * 6096) / (450 * 450) = 183.512178 184 slabs
How many 450mm x 450mm garden slabs do you need for garden area of 21ft x 19ft?
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.
How many 450mm x 450mm slabs would you need to build a 10ft x 8 ft shed base?
You need only 8 and half sheets of slab.
How many paving slabs would you need for a square meter if flags are 600mm x 450mm?
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
How many slabs would you need for a square meter if flags are 450mm x 450 mm?
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.

How many paving slabs would you need to cover 5 meters x 8 meters if flags are 450mm x450 mm?
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.
