Problem:
the Washington monument is 555 feet tall. you are asked to create a drawing using a scale of 5 feet= 1 centimeter. how many centimeters tall will the monument be in your drawing​,
Solution:
Consider the following diagram:
Thus, by cross-multiplication we get:
[tex]x\text{ cm = }\frac{555\text{ f}eet\text{ x 1 cm }}{5\text{ f}eet}=\text{ 111cm}[/tex]
Then, we can conclude that the correct answer is:
[tex]\text{111cm}[/tex]
