0.5*(n2-3n) where n equals the number of sides of the polygon
You cannot. There is not enough information.
A formula is needed to find the area of a parallelogram. It is a very simple formula which notates Area = base x height.
A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.
a squished rectangle
If you have the lengths of the two sides and a diagonal, then you can use Heron's formula to find the area of one triangle and double it for the area of the parallelogram.If you have two sides and an angle, then area = a*b*sin(C).
You cannot. There is not enough information.
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
two congruent triangles
The formula to find the surface area of a parallelogram is Base*Height.

no

you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
a squished rectangle
A parallelogram has two diagonals the same as all 4 sided quadrilaterals
If you have the lengths of the two sides and a diagonal, then you can use Heron's formula to find the area of one triangle and double it for the area of the parallelogram.If you have two sides and an angle, then area = a*b*sin(C).
No. Most do not.
