Original length, L
Original width, L/3

The "if" part of description
%28L-3%29%28L%2F3%2B2%29=12

Maybe a little bit easier to multiply both sides by 3.
%28L-3%29%2A3%28L%2F3%2B2%29=3%2A12
%28L-3%29%28L%2B6%29=36-------------------Factors of 36 which can work, 3 & 12.


L-3=3, and L+6=12;
Solve either or both for L.
