There are infinitely many of them. Any rectangle with dimensions 2*a where a > 22 cannot b made. So, 2*23, 2*24, 2*25, and so on.
Oh, dude, let me break it down for you. So, you can make a rectangle with 1 tile, 3 tiles, 5 tiles, and so on up to 45 tiles. That's like, 23 different rectangles in total. But hey, who's counting, right?
If you have to use all of them, 1.
Using all five tiles, only one rectangle can be made. (1 tile wide by 5 tiles long) Using less than all five tiles, you could make six different rectangles. (squares are technically rectangles too.) The rectangles possible would be: 1 tile wide by 5 tiles long, 1 wide by four long, 1 wide by 3 long, 1 wide by 2 long, 1 wide by 1 long, and 2 wide by 2 long.
