Answer 1

The model is 64.62 inches or 5.39 feet tall .

Step-by-step explanation:

Given:

Height of the Willis Tower in Chicago = 1,454 feet

Scale of the model = 2 inches : 45 feet height

To Find:

the height of the model = ?

Solution:

Let the height of the model be x

Then

`\text{Height of the model} = \frac{ \text{Height of the Willis Tower in Chicago}}{\text{Scale in feet} }* \text {Scale in inches}}`

On substituting the given values

Height of the model =
`(1,454)/(45) * 2`

Height of the model =
`32.31 * 2`

Height of the model = 64.62 inches

Converting into feet,

1 inch = 0.0833333 feet

so

`64.62 = 0.083 * 64.62 = 5.39` feet
