**drwls**, Tuesday, November 6, 2007 at 9:56pmLet L be the long dimension of the rug and W be the narrow dimension.

L W = (1/2) 12 x 16 = 96

For equal borders all around,

16 - L = 12 - W

Solve those two simultaneous equations.

L - W = 4 = L - 96/L

L^2 -4L +96 = 0

(L-12)(L+8) = 0

Choose the positive root.
