The answer will depend on the size of the patio slabs.

You want to convert 50 cm to meters.Since there are 100 centimeters in a meter....50 cm = 50 cm x (1/100) m/cm = 0.5 mAlong one side there will be ...8 meters/(0.5 meters/slab) = 16 slabsIn total there will be 16 x 16 = 256 slabs (Draw a diagram to appreciate why)To do conversions and simple math I recommend the Google Calculator. Go to the WikiAnswer http://wiki.answers.com/Q/In_detail_how_do_you_convert_units for more details.
Each slab is .5 x .5 = .25 square m. Yard is 8x 5 = 40 square m so you need 40/.25 = 160 slabs

1 slab of 1200 metres x 450 metres will certainly cover 1600 square metres. You may have trouble moving it into position, though.
Depends on the linear dimensions of both the slabs and the ground.
You will need 63 44cm x 44cm slabs to cover that area.

A square slab measuring 0.6 metres all round has an area of 0.36 square metres. This means that to cover an area of 24 square metres you will need 66 slabs and 2/3 of a slab. Covering the area may be problematic if 1/3 of a slab and 2/3 of a slab become involved, of lesser fractions, depending on the exact length and width which gave the area of 24 - and if there is a pattern to maintain.
Online you can purchase patio paving slabs, also known as pavers, can be found on eBay, Pronto and Improvements web sites. You can also purchase them locally at Lowe's and Walmart.

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.

4.9382716 to be precise, so 5, 450x450 slabs in a square metre.
