Instruction:
Divide the grid into rectangles along the grid lines such that each cell is in exactly one rectangle and each rectangle contains exactly one given quadrilateral symbol (black diamond or white bar). Each black diamond must be in a rectangle where the height and the width are the same. Each white bar must be in a rectangle where the height and the width are different. Any two rectangles that touch along at least one cell edge must have different areas.
