Answer:
The height of the building that casts a shadow of 78m meters is 39m
Step-by-step explanation:
Let height be represented by H and the shadow is S
as they are directly proportional
H s
H=KS ( where K is a proportionality constant)
H=2.5m , S= 5m
On substituting in the equation
2.5 = K*5
K= 0.5
Now the equation becomes
H = 0.5*S
Height when shadow is 78m
H= 0.5*78
H= 39m
