Best Answer

perimeter of a parallelogram = 2(w+h) where:

w is the base length of the parallelogram

h is the side length

If 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.

Why do you not usually multiply the side lengths of a parallelogram to calculate its area?

To find area you need base and height of a parallelogram. A = BH Not all the side lengths given would be base or height. Side lengths are perfect to find perimeter but don't rely on the side lengths for area.

How do you find the perimeter of a parallelogram when there are no given side lengths?

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


How many pairs of parallel sides does a parallelogram have?

A parallelogram has 2 sets of parallel sides. The opposite sides are equal in length and opposite angles are equal. Examples of parallelograms are squares, rectangles and rhombuses. You can find the perimeter of a parallelogram by doubling the base+side length.
