A^2 + b^2 = c^2 in right triangles.
4^2 + b^2 = 8.5^2
16 + b^2 = 72.25
b^2 = 56.25
b = 7.5

Answer
She used 6/15 litres of oil in January
Explanation
We are given that, in January, she used 3/5 of the amount of oil she used in February.
We are also given that, she used 2/3 litres of oil in February.
Therefore, amount of oil used in January is:
3/5 • 2/3 = 6/15
She used 6/15 litres of oil in January
11/12 divided by 3/4
11/12 • 4/3 (multiply by the reciprocal)
OR
Multiply from top to bottom
(11•4) • (12•3) = 44/36
Simplify (Divide top and bottom by the highest common factor... which in this case is 4)
Answer: 11/9
