Answer:
The answer to your question is:
length = 12
width = 6
Explanation:
Perimeter of a parallelogram = 2 length + 2 width
We know that width = length - 6
So
60 = 2 length + 2(length -6)
60 = 2 length + 2 length - 12
60 - 12 = 4 length
48 = 4 length
length = 48/4 = 12 meters
width = length - 12
= 12 - 6
= 6
