Answer:

108 m

Step-by-step explanation:

If the shadow is 0.8 m but actual parking meter is 1.2 m it means the shadow shrinks original by a factor of \frac {0.8}{1.2}=\frac {2}{3} similarly, if the shadow for the building is 72 m it means it has already been shrunk by a factor of \frac {2}{3} and to get the actual height of the building then we can say that the height be A

A\times \frac {2}{3}=72\\A=\frac {72\times 3}{2}=108 m

Therefore, the actual building is 108 m
