Help with stretch command

Hi

I currently have created a title block which is a 8.5"x11" at a scale of 1:1 (see dgn drawing).

I have been trying for awhile now to make this a 11"x17" landscape drawing at a scale of 1:1 using the stretch and scale and various commands to make this work but nothing is working. Can someone help me make this and explain to me how they did this so I can learn.

Any help would be appreciated..
