Remember that "mathematically similar" means that the ratio of side lengths is the same.
So the first step is to draw out the rectangles, making sure to rotate them appropriately so that they're in the same orientation.
Then you can let AE = x cm, and write the equation x/4 = 4/10 -> x = 1.6 cm.
Thus area ADEF = 1.6 * 4 = 6.4 cm^2. Hopefully that's right.
