I can’t figure this out I need the answer
fredd [130]

Answer:

  • Area 2 = 72 cm²
  • CD = 7 cm

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
