Question 1037606: A rectangular room is 10 feet longer than it is wide. One-Foot-By-One-Foot tiles cover the entire floor. Let w represent the width (in feet) of the room. Write an expression in simplest form that represents the number of tiles along the outside of the room.

If the width is w, and the length is w+10, then the perimeter is 2w+2(w+10), so you need 4w+20-4,or 4w+16 tiles (you don't want to count the corners twice)!!!!!!!!!!!!!!
