# Random Strip Widths

Planks are in 3 different widths which has to be randomly divided over the length of the wall: 145 mm - 50%, 95 mm - 30%, 46 mm - 20%  and the gap between planks is 10 mm.

```d
//Facade dimensions
l = 2;
h = 2;

//Panel widths
pw1 = 0.145;
pw2 = 0.095;
pw3 = 0.046;
spc = 0.010;

pw11 = pw1+spc;
pw21 = pw2+spc;
pw31 = pw3+spc;

//Panel count percentage
pwn1 = Math.Floor((0.5*l)/pw11);
pwn2 = Math.Floor((0.3*l)/pw21);
pwn3 = Math.Floor((0.2*l)/pw31);

pw12 = List.Cycle(pw11,pwn1);

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://gitbook.testingwaters.in/patterns/random-strip-widths.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
