To answer this I would set this up as a proportion. I would write 0.5 cm/1.5 m. Make this equal to x/36 m. x would be the scale measurement needed for the real height of 36 m. You can solve this proportion by using cross products to get 1.5x = 18 and solve for x. 18/1.5=12 cm. Or you can determine how many groups of 1.5 it would take to get to 36 (36/1.5 = 24). Then multiply 0.5 by 24 to get 12 cm.
