The answer is 50. First, you need to multiply 34.6 by 34.6, and multiply 15.4 by 15.4, and subtract the products which gives you 960. Next you subtract 15.4 from 34.6, giving you 19.2. Lastly, you divide 19.2 into 960 and you get 50.

Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
