Hello, Moo!

**3) Simple geometry**

The Swedish flag has a yellow cross of **constant** width in a blue background.

The yellow area represents one-third of the flag's area.

If the flag is 1m long and 66cm wide, what is the width of the yellow stripes ?

The stripes comprising the cross can be "moved" to the edges of the flag.

Let = width of the stripe (cm). Code:

100
* - - - - - - - - *
| | x
| * - - - - - - *
66 | | |
| | | 66-x
| | |
* - * - - - - - - *
x 100-x

The blue region's area is: . cm²

It is also: . cm²

Hence, we have: .

The Quadratic Formula gives us: .

The smaller root is the answer: . cm.
