Assuming that the floor squares are 11" x 11" and the dance floor is 9ft x 20ft, we can proceed as follows. 9ft = 108 inches and 20 ft = 240 inches. The product of the two which is the ares of the dance floor is 25920 square inches. Divide this by (11 x 11 = 121) to get 25920/121 = 214.214 squares. Since each package has 10 squares you would need 21.4214 packages. Since the shop keeper will not sell you fraction of a package plan on getting 22 packages.
