Final answer:
To find the original length when given a percentage of the length, set up a proportion and solve for the unknown value.
Step-by-step explanation:
To find the original length, we can set up a proportion using the given information.
Let's assume that the original length is represented by x metres.
We know that 6% of the length is equal to 570 metres, so we can write the proportion:
6/100 = 570/x
Cross-multiplying and solving for x, we get:
x = (570 * 100) / 6 = 9500 metres
