### Example Question #4 : How To Find The Perimeter Of A Parallelogram

Find the area of a parallelogram with base length  and side length .

Not enough information provided

Not enough information provided

Explanation:

The area  of a parallelogram with height  and base  can be found with the equation . However, while we have been given the length of the base and of another side of the parallelogram, we still do not know the length of the base. Therefore, we do not have enough information to find the area.

### Example Question #5 : How To Find The Perimeter Of A Parallelogram

Find the perimeter of a parallelogram with a height of , a base of , and a side of length

Explanation:

The perimeter of a parallelogram is the sum of the length of its sides. Since we know the length of the base and of another side, we know that the remaining sides of the parallelogram match those lengths. Therefore:

### Example Question #101 : Quadrilaterals

Find the perimeter of the parallelogram if h=, b=, and c=.

Explanation:

In order to find the perimeter, find the sum of each OUTER side:

Notice the height isn't used in this calculation.

Keep in mind that the sides directly opposite of each other are of the same length. This is why we have  and  appearing twice in our work.
