Sometimes those rectangles could be squares, which are by definition a type of rectangle.
Yes cutting a rectangle in half (either horizontally or vertically) will yield two smaller rectangles (each of which is the same size and shape as the other).
You divide the shape into smaller shapes you can calculate, like rectangles and triangles. If the shape is irregular, you have to approximate, for example by dividing it into many narrow rectangles. This technique is called "integration".
You should break it down in to smaller shapes. Two rectangles. Then figure out all the lengths. Multiply to find the area of the two rectangles. then add the products to get the final area.

The width of a polygon will depend on its shape. For a polygon, in general, it is the length of the largest diagonal. However, for rectangles of squares it often refers to its smaller sides.

The solid shape/figure that has six rectangles as faces is called a rectangular prism. The general term for any shape with six faces, regardless of shape is a hexahedron.
I assume you mean the calculation required. Split the irregular shape up into shapes for which you can find the area (eg rectangles, triangles), then the area of the shape is the sum of the areas of the smaller shapes.
