Solution

$We know that : 1 foot = 12 inches . Length of building = 120 ft = 120 \times 12 inches = 1440 inches Breadth of the building = 42 ft = 42 \times 12 inches = 504 inches Now, length of the boundary of building = 2 (length + breadth) = 2 (1440 + 504) = 2 \times 1944 = 3888 inches Length of each step = 30 inches Number of steps taken to take one trip around building = \frac{3888}{30} = 129.6 \approx 130$
