3-83.

Look back at problem 3-63 if you are not sure about using generic rectangles.

We can see that 3 is a factor of both 150 and 6, so we can put it on the diagram as shown.
Then we can see that 50 belongs at the top.

Again, reference problem 3-63 as a guide for this problem. Remember that you are adding the smaller areas to find the total area.
