1998 AIME Problem 12

Let ABC be equilateral, and D, E, and F be the midpoints of \overline{BC}, \overline{CA}, and \overline{AB}, respectively. There exist points P, Q, and R on \overline{DE}, \overline{EF}, and \overline{FD}, respectively, with the property that P is on \overline{CQ}, Q is on \overline{AR}, and R is on \overline{BP}. The ratio of the area of triangle ABC to the area of triangle PQR is a + b\sqrt {c}, where a, b, and c are integers, and c is not divisible by the square of any prime. What is a^{2} + b^{2} + c^{2}?

Leading zeroes must be inputted, so if your answer is 34, then input 034
