We can find the perimeter of the room by adding up the lengths of all the sides:
12 + 10 + 15 + 12 = 49 feet
Since James is using 12 ft wide carpet strips, he will need to buy enough linear feet to cover the perimeter of the room in 12 ft increments. To do this, we can round up the perimeter to the nearest multiple of 12:
Round(49, 12) = 48
Therefore, James will need to buy 48 linear feet of carpet. Answer: \boxed{48}.
