Answer:

  2 1/17 ft²/ft²

  square feet of old for each square foot of new

Explanation:

The area of the old patio is ...

  A = LW = (12.5 ft)(8.4 ft) = 105 ft²

The area of the new patio is ...

  A = (6.8 ft)(7.5 ft) = 51 ft²

Then the comparison of areas of old to new gives ...

  old patio area : new patio area = (105 ft²)/(51 ft²) = 2 1/17 ft²/ft²
