Answer:

The length of the parallelogram is 20 meters

The width of the parallelogram is 12 meters.

Step-by-step explanation:

Let's call x the length of the parallelogram and y the width of the parallelogram.

If the perimeter of the parallelogram is 64 meters, we can write the following equation:

2x + 2y = 64

Because the perimeter is 2 times the length added to 2 times the width.

On the other hand, the width of the parallelogram is 8 meters less than its length, so:

y = x - 8

Now, we can substitute y = x - 8 on the first equation as:

2x + 2y = 64

2x + 2(x - 8) = 64

Solving for x, we get;

2x + 2x + 2(-8) = 64

4x - 16 = 64

4x - 16 + 16 = 64 + 16

4x = 80

4x/4 = 80/4

x = 20

So, y is equal to:

y = x - 8

y = 20 - 8

y = 12

Therefore, the length of the parallelogram is 20 meters and the width is 12 meters.
