Since we're arranging squares, I'm assuming the arrangements are all going to be only two-dimensional and no stacking is allowed. If you have played tetris before, you'll know that can be arranged into :
1) A straight line
2) A 2 by 2 square
3) A T-shape
4) A L-shape
5) An inverted L-shape
6) A ladder
7) An inverted ladder
That's all the seven different arrangements for four squares.

Since there are 4 letters, they can be arranged 4! ways (4*3*2*1) or 24 ways.
It is 6!/3! = 6*5*4 = 120 ways
Rebecca = 7 letters 7! is 7 * 6 * 5 * 4* 3 * 2 = 5040 different ways -----------------------------

If this is for homework, I would state your reasoning for excluding (or including) that set. Count all the options up, and you have 8 different ways you can arrange the rows with the exclusion.

You can arrange 4 in 2 ways 1x4 and 2x2.

There are 4 distinguishable letters in the word fish, so there is 4! or 24 different ways can you arrange the letters in the word fish.
