It's a prime number. Therefore the only rectangular array it has is 1*73 (or 73*1)
13...13x1.
A rectangular prism is the only shape that is made up from only rectangular faces. But there are countless shapes which contain rectangular faces along with other shapes.
A rectangular prism or cuboid.
There are many shapes that have one and only one rectangular face, but an example of one would be a rectangular pyramid.

Yes, you can arrange 25 cans into arrays. An array is a rectangular arrangement of objects in rows and columns. For 25 cans, you could arrange them into a 5x5 square array, with 5 cans in each row and 5 cans in each column. This would give you a total of 25 cans in a neat and organized layout.
No, they are the only numbers that are NOT rectangular in shape. (I think you knew this and screwed up your question.) That is, all non-primes can be arranged into the form of a rectangle - e.g. 21 can be organized as a rectangle with dimensions of 3 x 7. But prime numbers cannot be organized as rectangles.
A rectangular prism, it has 6 rectangular faces.
leakage in arrays occur when you declare an array with big size and using only very few bytes.
It's actually not true. In order to make a good program which can work with big arrays you have to use dynamic arrays because you can cleam memory used by dymanic arrays any time. For static arrays is not true, memery which was reserved for static arrays will be available for other applications only when you finish working with your application (which is working with static arrays).
There are lots of non-rectangular flags: many of the flags used for maritime signalling are non-rectangular. The only non-rectangular national flag belongs to Nepal.

The foreach construct simply gives an easy way to iterate over arrays. Foreach works only on arrays (and objects).
