Question

A building has a shadow that is 18 feet long. Will is 5 feet tall, and he is standing next to the building. Will has a shadow that is 3 feet long. Use this information to complete the statement about the building.

Answer 1

Answer:

the answer is 30 feet

Answer 2

Answer:

The height of the building is $30\ ft$

Step-by-step explanation:

Let

x--------> the height of the building

y------> the long of the shadow of the building

m----> the height of Will

n-----> the long of the shadow of Will

we know that

By proportion

$\frac{x}{y}=\frac{m}{n}$

we have

$y=18\ ft$

$m=5\ ft$

$n=3\ ft$

substitute the values

$\frac{x}{18}=\frac{5}{3}$

$3*x=18*5$

$x=30\ ft$
