You can put this solution on YOUR website!
The area of the pool is A = 16*16 = 256
The area of the rubber floor is the same A=256

Let x = the width of the rubber covering.

Adding up the rubber area by breaking it up into 4 pieces (try drawing a picture to visualize it), we find:
16x + 16x + (16-2x) + (16-2x) = 256
32x + 32 - 4x = 256
28x = 224
x = 8

If you need a picture of it, let me know.
