Question 1752
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 * 12 = 120 ft^2 }}}.

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*a + 2*b }}}, 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*12 + 2*10 = 24 + 20 = 44 ft }}}.  So Jim needs 44ft of base board.
