Problem: one side of a rectangular field is 15 m and one of its diagonals is 17 m . find the area of the field .
Rationale: "other side = ( ( 17 ) 2 - ( 15 ) 2 ) ( 1 / 2 ) = ( 289 - 225 ) ( 1 / 2 ) = ( 64 ) ( 1 / 2 ) = 8 m . area = ( 15 x 8 ) m 2 = 120 m 2 . ans : a"
annotated_formula: rectangle_area(15, sqrt(subtract(power(17, const_2), power(15, const_2))))
