To solve the problem we must know about the Ratio.

What is Ratio?

A ratio shows us the number of times a number contains another number.

The length of the living space, in reality, is 21 meters.

Given to us

  • The scale is given as 2 centimeters equals 2.5 meters.

To find

  • the actual length of the living space if the length of the scale drawing is 16. 8 centimeters

Scale ratio

As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as

[tex]\dfrac{\text{Length of the scale drawing}}{\text{Length in reality}} = \dfrac{2\ cm}{2.5\ meters}[/tex]

Length of the living space

Using the same scale ratio,

[tex]\dfrac{\text{Length of the living space in scale drawing}}{\text{Length of the living space in reality}} = \dfrac{2\ cm}{2.5\ meters}[/tex]

[tex]\dfrac{16.8}{x} = \dfrac{2\ cm}{2.5\ meters}\\\\x=\dfrac{16.8 \times 2.5}{2} = 21\ meters[/tex]

Hence, the length of the living space, in reality, is 21 meters.
