There is street parking available in the village of Weald. This is a relatively simple puzzle, the information below will help you to solve it and might assist with a slightly harder one placed close by.
For this puzzle the diagram includes both rectangles and squares as a single layer.
The first example has a single square with a half size rectangle on each side. There are two small rectangles (1 unit), one square (2 units), two mid-size rectangles (3 units) and one large rectangle (4 units). A total of 6 rectangles

The second example has an additional square added. Now there are two small rectangles (1 unit), two squares (2 units), two mid-size rectangles (3 units), one rectangles of 4 units, two rectangle of 5 units and one rectangle of 6 units. A total of 10 rectangles.

So to the puzzle.

If the number of rectangles in the diagram is ab the cache is located at
N51 12.(a+a+a+b)(a+a)(b) E000 09.(a+b)(b-b)(b)
