Answer 1

Answer:

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

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

On substituting the given  values

Height of the model = $\frac{1,454}{45} \times 2$

Height of the model =$32.31 \times 2$

Height of the model = 64.62 inches

Converting into feet,

1 inch =  0.0833333 feet

so

$64.62 = 0.083 \times 64.62 = 5.39$ feet
