If you answer 42x42,the answer is1 764 arrays.
42
There are infinitely many possible answers. For example, 10*4.2, or 72*7/12
A yard is 3 feet 42 / 3 = 14 yards
6,394 divided by 42 = = 152.23809523809524
If you answer 42x42,the answer is1 764 arrays.
4 (or eight if you count transposed arrays as being different).
1*422*21 3*146*7
The prime factorisation of 42 is 2*3*7.

There are many possible answers. 1 times 42 is a convenient pair of numbers.
There are infinitely many possible answers. The simplest is 1 times 42. Other examples: 10 * 4.2 -3 * -14
7 of them.
41+1 = 42 is one of infinitely many possible answers. 40.879 + 1.121 = 42 is another.
42 combinations.
There are infinitely many possible answers. Let X > sqrt(42) be any number and let Y = 42/X. Then XY = X*42/X = 42 and since the choice of X is arbitrary there are infinitely many solutions. 10*4.2 is one such.
