Answer:
Step-by-step explanation:
For similar figures, side lengths (and any other linear measure) are proportional. Areas are proportional to the square of the scale factor for side lengths.
   Perimeter 1/Perimeter 2 = CD/EF
   21/18 = CD/6
   CD = 6(21/18)
   CD = 7 . . . cm
__
   Area 2/Area 1 = (Perimeter 2/Perimeter 1)²
   Area 2/98 = (18/21)²
   Area 2 = 98(6/7)²
   Area 2 = 72 . . . cm²
