Question

Rectangle,area is not known is divided into 4 unequal parts. Area of 3 small rectangles known. Area of 4th ?

Answer 1

if you cannot specify dimensions do it like this. draw out the rectangles that you know the figures for. fit them into an area that looks like a larger rectangle with a chunk missing. you can now find the dimensions because they will also belong to two of the other rectangles

Answer 2

Unless some specific dimensions or ratios are given, we can't solve this problem for you.

Do you have a diagram you can link to or post (say on imageshack.us)?
