Problem: calculate the area of a triangle , if the sides of are 52 cm , 48 cm and 20 cm , what is its area ?
Rationale: "the triangle with sides 52 cm , 48 cm and 20 cm is right angled , where the hypotenuse is 52 cm . area of the triangle = 1 / 2 * 48 * 20 = 480 cm 2 answer : a"
annotated_formula: multiply(divide(48, const_2), 20)
