You need to take the magnitude of the cross-product of two position vectors.
For example, if you had points A, B, C, and D, you could take the cross product of AB and BC, and then take the magnitude of the resultant vector.
You multiply the base and the height of the parallelogram.
Not too sure of the given dimensions but the area of a parallelogram is length times perpendicular height.
Hopefully you've been given the parallelogram's area. If so you can use the following formula: Area of parallelogram = base length x altitude therefore altitude = area of parallelogram (divided by) base length
Too many dimensions have been given because the area of a parallelogram is length times perpendicular height.
You cannot. There is not enough information.

A square.

Multiply the height by the width

Any geometrical figure can have any area. Triangles can be constructed of any desired size, and so can parallelograms.
It depends upon the shape. For example, if it is a parallelogram, then divide the area by the height to get the base.
Do exactly the same thing for a rhombus or a parallelogram A = base x height (parallelogram) OR A = 1/2 x diagonal 1 x diagonal 2
