Will the carpet fit?
🎓 School maths · Years 4–6Measurement — area — Find the area of a rectangle with length × width.Maths by year →
The Case. You've got a new carpet — but will it fit your bedroom floor? To know, you need the area: how much flat space your room covers.
Your tools. A little maths — length × width — and matplotlib to draw your room to scale.
Investigate. Press Run. It works out your room's area in square metres and tells you if the carpet is big enough.
- Change the room size — when does the carpet stop fitting?
- Area = length × width. Builders and decorators use this every day.

Bundles your findings, chart and code into one PDF you can keep, print or hand in.
🧩 How this code works
The tools it uses
- Matplotlib — your crayon box — it turns numbers into charts and pictures.
How to read it, top to bottom
- 1. Import — bring in the tools (listed above).
- 2. The data — the lists and numbers near the top. These are the bits you change.
- 3. The work — a little maths, or a loop that repeats a step.
- 4. Show it —
print(...)writes words;plt.show()draws the picture.
Use it for your own problems
- Change the numbers at the top and press Run — nothing breaks, so experiment!
- Ask your own version of the question — swap in your family, your scores, your week.
- The same tools work on any numbers — that's the superpower you're learning.

Area = length × width. A 5 by 4 room covers 20 squares, each one metre across.
