Answer:

Model = 80cm

Step-by-step explanation:

Given

Length = 19.2\ m

Scale=1:24

Required

Determine the scale measurement in centimeters

The scale can be represented as: Model : Actual

Scale = Model : Actual

Substitute 19.2 for Actual Length

Scale = Model : 19.2\ m

Represent as a fraction

Scale = \frac{Model}{19.2m} --- (1)

Recall that:

Scale=1:24

Represent as a fraction

Scale = \frac{1}{24} --- (2)

Equate (1) & (2)

\frac{Model}{19.2m} = \frac{1}{24}

Multiply through by 19.2m

Model = \frac{1}{24} * 19.2m

Model = \frac{ 19.2m}{24}

Convert to centimeter

Model = \frac{ 19.2 * 100cm}{24}

Model = \frac{ 1920cm}{24}

Model = 80cm

<em>Hence, the length of the scale model is 80 cm</em>
