Making the assumption, not justified by any information in the question, that the tiles are 18 inches by 18 inches in size and not some other units eg 18 cm2,

each tile covers 1.5ft*1.5ft = 2.25 sq ft.

To cover 1700 sq ft will require 1700/2.25 = 755.55... tiles or 756 tiles.

However, this assumes that ALL offcuts are used - a totally unrealistic assumption. Depending on your skill level, you should allow 5-10% extra.
