x for width, 2x for length.
Area enclosed, x%2A2x=2x%5E2.

Area must be more than 98 square meters.
2x%5E2%3E98
x%5E2%3E49
x%3E7

The width must be at least 7 meters and length must be more than 14 meters;
OR
The width must be more than 7 meters and length must be at least 14 meters.
Also
Another choice acceptable,
Both width be more than 7 AND length be more than 14 meters.
