Area Logic: Rectangle Puzzles

Find the "?" using only the numbers on the figure.

Each puzzle is a shape made of rectangles, with the areas of some of them written in. All you need is area = width x height, plus simple whole-number arithmetic. No auxiliary lines, no fractions, no equations. Yet the higher levels take 5 to 8 steps of pure deduction.

EVERY PUZZLE HAS ONE ANSWER
Every puzzle is machine-verified: the given numbers determine a single answer, and every intermediate value is a whole number.
