One metre=10 decimetres.
Therefore 30 metres = 30*10=300 decimetres.

Solve the difference
The question you posted included the solution. However, the solution is incorrect;
The absolute difference is represented as:
In this case:
So, the distance is calculated as:
Open bracket
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
To use the angle-angle similarity theorem you need to know 2 corresponding angles of each triangle are the same.
You are already shown that angles H and M are the same.
The sets of corresponding angles are:
H and M, N and I, and O and J
The answer would be angle O and angle J are similar.
