Let x = length
Let y = width
2x%2B2y=300 according to perimeter description.
We want x%3Cy because two lengths are used for
fence but only one width, and we have a cost restriction.
Cost: 50%2A2x%2B50%2Ay%3C=12000.

The judgement of x%3Cy is mostly a logical feeling, and not certain if it is really correct. First just use the system:
highlight_green%2850%2A2x%2B50y%3C=12000%29 and highlight_green%282x%2B2y=300%29 and see what happens. Simplify each of those statements before using them.
