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!

Answer:
Step-by-step explanation:
Left to right, the A, B, C
A = turn 180° reflect along y-axis
B= turn 90° reflect along x-axis
C= reflect along y-axis move 2 down
If the Length is 5 feet longer than the width then we can say the width is X and the length is X+5. If the perimeter is 170 feet then we can calculate the perimeter as
X+(X+5)+X+(X+5)=170 feet
2X+2 (X+5)=170 feet
2X+2X+10=170 feet
4X+10=170 feet
4X=170 - 10 feet
4X=160
X=160/4
X=40
so the width of the garden is 40 feet and the length is 40+5=45 feet
(5 * 1/3) * 3 = 5 * (1/3 * 3)
the associative property of multiplication allows us to regroup the numbers without changing the answer
(5 * 1/3) * 3 = 5/3 * 3 = 15/3 = 5
but by regrouping, it is much easier
5 * (1/3 * 3) = 5 * 1 = 5
another example..
(6 * 2/3) * 3/2 =
12/3 * 3/2 =
12/2 =
6
but by regrouping...
6 * (2/3 * 3/2) =
6 * 1=
6
