Turner's mom measured his room to see how long the wallpaper border needed to be. if two walls are 15 feet long and two walls are 12 feet long, how long should the strip of border be cut?

  54 feet

Step-by-step explanation:

The perimeter of the room is the sum of wall lengths:

  2·(15 feet) + 2·(12 feet) = 30 feet + 24 feet = 54 feet

The border should be cut to 54 feet.

Comment on the question

This seems to be a math problem designed to get you to figure the perimeter of the room. If you were actually installing wallpaper, you might want to cut the border in four (4) pieces, each slightly longer than the corresponding wall. That way any lack of squareness in the corners could be managed more easily, and the possibility of a gap at the seam could be eliminated.

25/6 hope it : )
