400 length split into x and y.
Each of these, becomes perimeter x for smaller field, and perimeter y for large field.

Each is square shape, so side length for small field is ; side length for large field is .

, from second part of the description.

The original 400 cm length also allows the equation, .

Solve this system for x and y:

----this option is meaningless.
