You can put this solution on YOUR website!
Call the depth and width, d and w respectively. Then
d = w + 3 and
2d = 6 + 2w
There is a problem with the exercise because you can double the first equation and get the second. Therefore there are an infinite number of solutions.
w=5 and d=8
w=20 and d=23
are two...
