Answer:
So W is going to stand for width and L is going to stand for length.
L= 2W+6
78=2L + 2W
Those are the two equations you will use. So plug in L=2W+6 into the other one and solve.
78= 4W+12 +2W
(simplify)
78=6W+12
(-12 from both sides)
66=6W
(divide by 11)
W=11
Replug W into your equation to find L.
L=22+6
(simplify)
L=28
I hope this is right
Step-by-step explanation:

For maximum area, we take first derivative and then equalize it to zero
<span>A(x) = 27x- x^2 </span>
<span>A'(x) = 27 - 2x </span>
<span>Set that equal to zero and solve for x : </span>
<span>27 - 2x = 0 </span>
<span>27 = 2x ......................... [ added 2x to both sides ] </span>
<span>13.5 = x ........................ [ divided both sides by 2 ] </span>
So the area will be
<span>A = 27(13.5) - (13.5)^2 </span>
<span> = 364.5 - 182.25 </span>
<span> = 182.3 ft^2 </span>
It would be greater
48.51 > 48
