Option (1)
Step-by-step explanation:
Area of the composite figure ABCDEFGH = Area of rectangle ABGH - Area of rectangle CDEF
Area of rectangle ABGH = Length × Width
                     = 14 × 7
                     = 98 cm²
Area of rectangle CDEF = 9 × (7 - 4)
                    = 27 cm²
Area of the composite figure = 98 - 27
                        = 71 cm²
Option (1) is the correct option.
