Final answer:
To find the original length, set up a proportion and solve for 'x'. The original length is 9500 meters.
Step-by-step explanation:
To find the original length, we need to determine what length represents 6% of it. We can set up a proportion to solve this. Let's call the original length 'x'. The proportion would be:
6% / 100% = 570 m / x
To solve for 'x', we can cross-multiply and then divide:
6x = 570 * 100
6x = 57000
x = 57000 / 6
x = 9500
The original length is 9500 meters.
