Step-by-step explanation:
All of the sides are the same length.



Ratio of height of the flag pole to the length of its shadow = 40:9.6 = 25:6
Ratio of height of the building to the length of its shadow = x:48 = 25:6
x/48 = 25/6
x = (48 x 25)/6 = 1200/6 = 200
Therefore, the height of the building is 200 feet.
