Let's do this using the process of elimination. Since you didn't include choice D, we can only use A, B, and C.
C: If we're finding the width of the patio, how is the thickness of the tiles going to help? C is wrong.
A: We already know the area (72), so how does knowing the perimeter help us? All we know using that information is that 2 pairs of numbers give us the perimeter & also multiply to get 72. But not <em>which</em> 2. A is wrong.
B: Pay more attention to the last part of B... "the length". Well, if we have the area (72), and we have the length, then we can do area/length-width to find the width. B is correct!

add the like terms
14x=-3+x
subtract x from both sides
13x=-3
divide both sides by 13
x=-3/13
10 • 10=
Is 10^2
In exponential form
