**PsyDAG**, Tuesday, March 3, 2009 at 9:43amLet S = shorter side, L = longer side and P = perimeter (all in meters).

2S + 2L = P ---> 40 + 2L = P

2S + 2(L - .3) = P/2 ---> 40 + 2(L - .3) = P/2

Substitute the value for P from the first equation into the second. Solve for L.

I hope this helps. Thanks for asking.
