Answer:
A(max) = (9/2)*L² ft²
Dimensions:
x = 3*L feet
y  = (3/2)*L   ft
Step-by-step explanation:
Let call  "x"  and  " y " sides of the rectangle. The side x is parallel to the wall of the house then
Area of the rectangle is  
A(r) = x*y
And total length of fence available is 6*L f , and we will use the wall as one x side then, perimeter of the rectangle which is 2x  +  2y   becomes x + 2*y
Then
6*L  =  x + 2* y    ⇒ y  = ( 6*L - x ) /2
And the area as function of x is
A(x)  =   x* ( 6*L - x )/2
A(x)  = ( 6*L*x  - x² ) /2
Taking derivatives on both sides of the equation we get:
A´(x)  =  1/2 ( 6*L - 2*x )
A´(x)  =  0      ⇒      1/2(  6*L  - 2*x ) = 0
6*L - 2*x  = 0
-2*x  = - 6*L
x  =  3*L feet
And
y  = ( 6*L - x ) /2   ⇒  y  = ( 6*L - 3*L )/ 2
y = ( 3/2)*L feet
And area maximum is:
A(max)  =  3*L * 3/2*L
A(max)  = (9/2)*L² f²
