# Square into three rectangles

Divide the square with a side length of 12 cm into three rectangles with have the same circumference so that these circumferences are as small as possible.

**Dr Math**

so the solution is

1. 12*3 ... a = 12 * b = 3

2. 9*6 ... c = 9 * d = 6

3. 9*6 ... c = 9 * d = 6

o1 is the circumference of the first, o2 the second, o3 the third rectangle

o4 is a circumference if the square is divided into same 12 * 4 rectangles

1. 12*3 ... a = 12 * b = 3

2. 9*6 ... c = 9 * d = 6

3. 9*6 ... c = 9 * d = 6

o1 is the circumference of the first, o2 the second, o3 the third rectangle

o4 is a circumference if the square is divided into same 12 * 4 rectangles
