Let the increase in width and length be x meters. The new width will be 12 + x and the new length will be 14 + x. The new area will be (12 + x)(14 + x) = 255. Expanding and simplifying this equation gives x^2 + 26x - 57 = 0. Solving this quadratic equation, we find x = 3 meters. Therefore, the new dimensions will be 15 meters wide and 17 meters long.
