Answer:
This question overall depends on a continuously changing factor.
Step-by-step explanation:
There are many houses in this world that have an area of less than 100 , while many others have up to 700, 800, or even 1000
of land. Your question is impossible to calculate because of the massive amount of houses in this world. If you want a good estimate, say around 0.9 to 1.8 billion.

Answer:
Height of the goalpost is 9.25 m.
Step-by-step explanation:
As per the rule of reflection in physics,
Angle of incidence = Angle of reflection
As we can see in the picture attached, both the angles (θ) are equal.
m∠ACB = m∠ECD = 90° - θ
m∠ABC = m∠ADC = 90°
Therefore, both the triangles ΔABC and ΔEDC will be similar.
And by the property of similar triangles, their corresponding sides will be proportional.
ED =
ED = 9.25 m
Height of the goalpost is 9.25 m.
