Answer:
24 ft
Step-by-step explanation:
The first step is to have uniform units hence we convert the inches to ft.
Conversion
1 inch is equal to 0.0833 ft hence 9 inches will be 9*0.0833=0.75 ft
The shadow of the man is 4.75 ft while actual height is 6ft
By cross multiplication concept, we evaluate that
6ft=4.75 ft shdow
X ft= 19 ft shadow
X=6*19/4.75=24 ft
Therefore, the actual beam height is 24 ft
