    Assume it's a rectangle, then |dw:1347066717259:dw| perimeter is all four sides added together, and length = width +14 inches. Go from there.

    Using 'L' for length and 'W' width, tell me in a mathematical way that the perimeter is 132 in.

    \[132=2l + 2w\]\[w+14=l\]\[132=2(w+14)+2w\]\[132=2w+28+2w=4w+28\]\[104=4w\]\[w=26 \]\[l=40\]
