Area of each paving slab = 0.45 m* 0.45 m = 0.2025 square metres
Therefore, number of pavers required = 15/0.2025 = 74.07 = 75 pavers.
That is the mathematical answer and assumes that the 15 sq metre area is well behaved. That is to say, all the offcuts can be used without compromising the appearance.

How many square paving slabs each of 50 cm are needed to cover a 8 m by 5 m rectangular yard?
Each slab is .5 x .5 = .25 square m. Yard is 8x 5 = 40 square m so you need 40/.25 = 160 slabs
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.
How many paving slabs 300mm x 300mm needed to pave 22sqmtr?
Area of paving slab = 0.3 m * 0.3 m = 0.09 sq metres. So number of slabs required = 22/0.09 = 244.44.. recurring = 245. However, that is the minimum mathematical answer. In real life you may well require more if the area to be covered is awkward or if you do not want to use all the off-cuts and end up with a mosaic.
