First, there is no such word as trapozoid: it is trapezoid although most of the world know it as a trapezium.
Whereas a trapezium has one pair of parallel sides, a parallelogram has two pairs of parallel sides.

A quadrilateral is a parallelogram with four sides. For example: square, rectangle, parallelogram, trapezoid, rhombus, diamond...

It depends entirely on their relative shapes and sizes. They could make a triangle, a parallelogram, a square, or a pentagon or even a concave heptagon.
You cannot because area is a two dimensional concept which cannot be measured in feet, which are one-dimensional.
A quadrilateral that is not a parallelogram (two sets of parallel sides) may be a trapezoid or a trapezium (US terms). To draw a trapezium (irregular quadrilateral), draw two parallel lines and connect them with unequal lines at non-congruent angles. If you make the angles opposite and congruent, you have drawn a trapezoid, which looks like a small stepstool with a top smaller than the base. If you make the connecting lines of equal length, you have drawn a trapezoid or parallelogram.
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
