What is a ratio?
In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.
Given that:-
- In the diagram, a building casts a 35-ft shadow and a flagpole casts an 8-ft shadow. If the flagpole is 18 ft tall,
The height of the building will be calculated as:-
Let the height be x ft. Now the ratio of the actual height of the building and flagpole and the shadow of the building and the pole will be the same.
\(\dfrac{35}{18}=\dfrac{x}{18}\\\\\\x = \dfrac{18\times 35}{8}\)
x = 78.75 ft
Therefore the height o the building will be equal to 78.75 ft.
