58.5 & 16.5....

2*84 3*56 4*42 6*28 7*24 8*21 12*14

1 x 42, 2 x 21, 3 x 14, 6 x 7

3 multiplied by 14 is 42.

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.

The answer is cuberoot(42) = 3.476, approx.

2 x 3 x 7 = 42

1 and 252, 2 and 126, 3 and 84, 6 and 42, 7 and 36, 9 and 28, 12 and 21, 14 and 18.

21 and 4 14 and 6 28 and 3 12 and 7 42 and 2

For instance 4 and 10.5 or 3 and 14. 2 and 21 also works. There are many answers to your question.

2+21=23 2*21=42 (* is another symbol for multiply)
