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 [tex]\frac {0.8}{1.2}=\frac {2}{3}[/tex] similarly, if the shadow for the building is 72 m it means it has already been shrunk by a factor of [tex]\frac {2}{3}[/tex] and to get the actual height of the building then we can say that the height be A
[tex]A\times \frac {2}{3}=72\\A=\frac {72\times 3}{2}=108 m[/tex]
Therefore, the actual building is 108 m
