Problem: the length of rectangle is thrice its breadth and its perimeter is 72 m , find the area of the rectangle ?
Rationale: "2 ( 3 x + x ) = 72 l = 27 b = 9 lb = 27 * 9 = 243 answer : c"
annotated_formula: multiply(multiply(divide(72, add(multiply(const_3, const_2), multiply(const_1, const_2))), const_3), divide(72, add(multiply(const_3, const_2), multiply(const_1, const_2))))
