When finding the amount of square feet needed to cover a room, you should find the area of the given room. In this case the room is 10ft by 12ft, so the area is +10+%2A+12+=+120+ft%5E2+.
The second part is asking how many feet of base board you need to cover the perimeter of the room. The perimeter P of a rectangular room is given by +P+=+2%2Aa+%2B+2%2Ab+, where a and b are the lengths of the sides. In this case, a = 12ft and b = 10ft (you could reverse these but it doesn't matter), so the perimeter P is +P+=+2%2A12+%2B+2%2A10+=+24+%2B+20+=+44+ft+. So Jim needs 44ft of base board.
