The perimeter of the given rectangle is 
   2(6 cm + 8 cm) = 28 cm
The area of the given rectangle is 
   (6 cm)*(8 cm) = 48 cm^2

The larger rectangle will have a perimeter of
   6.5*28 cm = 182 cm
The larger rectangle will have an area of
   6.5^2*48 cm^2 = 2028 cm^2 . . . . . note the scale factor is squared for area

The appropriate choice is the 3rd one, ...
   Perimeter = 182 cm, area = 2,028 cm^2

Answer:

Perimeter = 182 cm, area = 2,028 cm^2
