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.

It depends on the units used for measuring the tiles. Obviously, the number of 18 inch x 18 inch tiles required will not be the same as 18 cm x 18 cm tiles. And if there were 18 yard x 18 yard tiles, you would need only 1.
No. You cannot form 24 using only 1 tile, for example.
How long is the rectangle? If the rectangle is only one tile long, then it will take 20 tiles.
1
Two tiles can only make one rectangle.
Only 1 rectangle can be built with a Prime number of square tiles.

Because prime numbers only have one factor pair.
If you can only make one rectangle, your number's prime. If you can make more than one, it's composite.
prime number
four
Any positive number other than 4. The only reason it cannot be 4 is that the shape would then be a square, not a rectangle. If you want to be more pedantic about it, you could say any number greater than 4, since the length of a rectangle should be larger than its width.
The length ad the width is 16 and 3 because 16 times 3 equals 48 and 16 plus 3 equals 19 which is a prime number because its only factors are 1 and itself
The skinny one. A prime number only has two factors (one rectangle). The factors are one and the number itself.
