If no side lengths are given, then no perimeter is defined.

Even if you know all four angles in the parallelogram, it could still be drawn on the

head of a pin or on the floor of the Grand Canyon, with the same angles.

But let's look on the bright side: If someone said to you "I have this parallelogram.

What is its perimeter ?", then you could pick any number you want out of the blue,

and he could not say that you're wrong. A parallelogram could be drawn that has

the perimeter you gave, and matches all the numbers that he gave.

How do you find the value of a parallelogram?

A parallelogram has no intrinsic value. It has sides of two different lengths, diagonals of two different lengths, a perimeter, an area, two value for interior angles. The question could refer to any one of them. Furthermore, the answer would depend on what information was available.


Can you find the perimeter if you know the lengths of two opposite side of a parallelogram?

perimeter of a parallelogram = 2(w+h) where:w is the base length of the parallelogramh is the side lengthIf you know the length of one side, then the opposite side must have the same length.This is not enough information to fine the perimeter since you have only h or w and not both.

How do you find the perimeter of a rectangle with only the slopes given?

You cannot. Given only the slopes, it is impossible to determine the distance between the parallel lines and so the lengths of the sides. Without that you cannot calculate the perimeter.
