The radius of the cylinder can be found by dividing the diameter by 2: 14 meters / 2 = 7 meters.
The formula for the surface area of a cylinder is A = 2πr² + 2πrh, where A is the surface area, r is the radius, h is the height, and π is approximately 3.14.
Plugging in the values, we get: A = 2 * 3.14 * 7² + 2 * 3.14 * 7 * 12
Simplifying this expression, we get: A = 2 * 3.14 * 49 + 2 * 3.14 * 84
A = 306.92 + 527.52
A = 834.44
Rounding to the nearest tenth, the surface area of the cylinder is approximately 834.4 square meters. Answer: \boxed{834.4}.
