Ooops! I made a mistake. Sorry.

i think it is A

To determine the possible length for the walkway using 18-inch square tiles, we need to consider the length of the walkway in feet and inches.
Since each tile is 18 inches, we should convert the given lengths to inches to see if they can be evenly divided by 18.
A. 6 ft = 6 * 12 = 72 inches
72 inches / 18 inches = 4 tiles
So, A is a possible length.
B. 10 ft 6 in. = 10 * 12 + 6 = 126 inches
126 inches / 18 inches = 7 tiles
So, B is a possible length.
C. 25 ft 6 in. = 25 * 12 + 6 = 306 inches
306 inches / 18 inches = 17 tiles
So, C is a possible length.
D. 32 ft = 32 * 12 = 384 inches
384 inches / 18 inches = 21.33 tiles
The result is not a whole number, so D is NOT a possible length.
Therefore, the correct answer is D.
