1^2 = 1
2^2 = 4*1 = 4
4^2 = 4*4 = 16
8^2 = 4*16 = 64 .... hmmm

Yup.  

Suppose the area of the big square is 16 square units, that means each side is of length four.  If the big area is 16 times the smaller area, that meas the smaller area is just 1 square unit and the length of each side is one unit in length.

So the length of one side of the bigger square is 4 times the length of the smaller square. :)
