you need 45 M in total so you need 15 m2 of each size for an even distribution type of pattern
you haven't specified the flag sizes or the pattern so cannot be more specific than that

I wrote/created a short exercise for the training group about calculating areas, but it never got used other than the one session I ran (and it probably never will be used again, given the parlous state of training at the moment). It was/is a Powerpoint thingy, and would need a bit more work to make it web-friendly, but I'm quite proud of it. For copyright reasons, I can't use the actual Powerpoint thingy that's already finished; I'd have to start again and do summat new, but it might be a nice project for the summer evenings.

sfulla, if you want to do this yourself, rather than use Tony's service (which will solve it very quickly and inexpensively), here's what you do:
First, determine the common demoninator in your slab sizes. Usually, it's 300mm, as you'll know if you laid before. A three size design would normally have 300x300mm, 300x600mm and 600x600mm (it was better when they were 1x1, 2x1 and 2x2 but hey ho).
If you can, adjust the paving size to the common demoninator, this will remove the need for cuts and give the paving a more consistent look, e.g., have 7.2m or 6.9m rather than 7m.
Re-do your total area calculation with the adjustments taken into consideration, add 5% (if from BM stock) or 10% (if special order) for breakages/spares/dodgy slabs. Robert is your father's brother.
