JAA ATP - G-Nav question

Currently having fun with the JAA ATP Question Database (QDB), particularly G-Nav. I’ve been trying for quite a while now, but I can’t figure out how to solve the following question, is there anybody who can help?

The QDB contains the following example asking two questions:

On a Lambert chart the distance between to parallels of latitude 2° is measured to be 112 millimeters. The distance between two meridians, spaced 2°, is, according to the chart 70 nm.

First question:
What is the scale of the chart, in the middle of the square described?
Correct answer would be 1 : 1 984 000

Second question:
What is the latitude in the center of the described square?
Correct answer would be 54°
