55. You not only have the 25 little squares, but 16 2X2 squares, 9 3X3 squares, 4 4X4 squares, and 1 large 5X5 squares.
Thus, it is the sum of 1^2 + 2^2 + 3^2 + 4^2 + 5^2 = 55.

Well, you have to count it up... Count up how many individual 1x1s fit in a 5x5(25). Then count up all the 2x2s (16) you can make. Then how many 3x3s(9). Then how many 4x4s (4) and lastly you have 1 5x5. They can overlap...
25 + 16 + 9 + 4 + 1 = 55
