Depending on how you combine them.You could have a trapezoid or a pentagon.
I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.
A triangle and parallelogram
Right Triangle
Not quite sure what to make of "combined". If they are disjoint, there are 9 sides. Otherwise, up to 15.
A trapezium
Bigger triangle, a parallelogram or a pentagon.
a pentagram

Like this: /\ / \ <-- triangle /__\ / /\ /__ /_\ <-- another triangle /\ | | Parallelogram
a parallelogram,a right triangle and a triangle
A parallelogram is two triangle together.

The answer depends on how the parallelogram in the triangle is constructed.
you join a triangle (with the point facing upwards) to an other triangle(this time the point facing downwards ) There you have it,a parallelogram ahhh yeah
you do it because the triangle is half the size of the parallelogram
NO!!!! A parallelogram has 4(four) sides. A Triangle has 3(three) sides.
