There's a confusing but easy way to solve this. However, I'm going to convert into improper fractions to make it easier.
To convert to improper fraction, take the whole number, multiply it by the denominator and add it to the numerator. All over the same denominator.


Subtract them.


Convert to mixed number by dividing.
65/10=6
60
----
5
The 6 is the whole number, 5 the numerator and 10 the denominator. Remember the negative sign that we had.

5 and 10 can be simplified
5/5=1
10/5=2
Our final answer would be:

Substitute the value of s, which is now 3 into the equation
A = 6(3)^2
A =6(9)
A = 54
Answer: 95metres for the length and the original cost is 2.105
Step-by-step explanation:
Let the initial length be x,
So, x+5=200/2
x+5=100
x=95
Note since the total price is the same and the original length is 95metres.
Therefore, the original cost per metre is
200/95=2.105
