The surface area can be calculated by adding the area of the rectangle and the areas of the two attached circles.
Area of rectangle = height * width = 18 * 15 = 270 yards^2
Area of one circle = π * (radius)^2 = 3.14 * (7.5)^2 = 176.625 yards^2 (since radius = diameter/2)
Total surface area = 270 + 176.625 + 176.625 = 623.25 yards^2
Therefore, the correct answer is 623.25 yards2.
