  12√2

  24√2

Step-by-step explanation:

The Pythagorean theorem tells you the square of the slant length is the sum of the squares of x and the height:

  (6√11)^2 = x^2 + (6√3)^2

  x^2 = 36·11 -36·3 = 36·8 = 144·2

  x = 12√2 . . . . length of 1/2 the house

The full length of the house is double this value:

  2x = 24√2 . . . . full length of the house

3x + 4y -25 =0 represents the amount of change sianna should recieve
