Well to find the perimeter of the room, you will want to add up all of the sides of the rectangle room. This basically is 10+10+12+12. This is the perimeter of the room in feet and how much total wall paper Martha will need. To find out how many packages she needs you want to divide the number you just got by 6 feet. Always round up if it is not a whole number because its better to have more paper than not enough.
