The Simpsons and their Mathematical Secrets

Can you solve this vexing vexillology problem?

You are asked to make flags for an event. The attending nations are Nepal, Japan, Czech Republic, South Korea, Bahrain, Bangladesh, and the Philippines.

  • They must be mathematically accurate.
  • They must all be 1.2m in height. (You can ignore the blue border when calculating the height of the Nepalese flag.)
  • Each piece of a single colour must be a single piece of fabric (i.e. cannot be made of multiple pieces of fabric put together).

The fabric you use is on a roll of 2.4m wide. You notice you only have 2m left on the roll of RED material.

  1. What flags can you make to produce the least wasted material, and how much material is wasted?
  2. What length of additional material would you need to make the remaining flags?
  3. What is the smallest length of this fabric that would allow you to make all the flags of this size?
