HOW TO...CONVERT A "WHITE PRINT" TO 1/35TH SCALE??

HI THERE, HEY THERE, HO THERE!!!

DR.-RAMA HERE, HI I'M THE NEW KID ON THE BLOCK. ANYONE KNOW HOW I CAN RE-SCALE THIS DRAWING INTO 1/35TH? IT'S A HALL WAY WITH A COUPLE OF ROOMS OFF OF EACH SIDE. I HAVE ONLY A FEW OF THE ORGINAL MEASUREMENTS FROM THE ORG. "BLUE-PRINT".THINGS LIKE....THIS WALL IS 9 FOOT TALL WITH A 7'6'' DOOR WAY, OR HALLWAY IS 4' WIDE. PLEASE, PLEASE HELP ME. I FEEL REAL STUPID ABOUT NOW, KNOWING THIS IS SOMETHING "EVERY REAL MODELER KNOWS ALREADY". EVERYONE EXCEPT ME. I'M GUESSING IT'S SOMETHING SIMPLE & I'M JUST NOT SEEING IT. I DO HAVE THE DELUX SCALE MODEL REFERENCE RULE BY "EXCEL" IF ONLY I KNEW HOW TO MAKE IT WORK, TALKING NICE TO IT DOESN'T SEEM TO GET ME VERY FAR. STARING AT IT FOR UNTOLD HOURS HASN'T HELPED ANY SO FAR EITHER. ALSO, IF IT'S JUST NOT TOO MUCH TO ASK ALL AT ONCE....I NEED HELP IN "HOW-TO-WIRE" THE LED'S TOGETHER WHEN WANTING TO USE ONLY A "PLUG-IN" TRANSFORMER DEVICE? THANK YOU, THANK YOU.
