Chapter 6.6, Problem 26STP

To determine

To Find: The scale factor of the blueprint.

Answer to Problem 26STP

The scale factor of the blueprint is $\frac{1}{12}$ .

Explanation of Solution

Given information:

Blueprint has a scale of $2inches=2feet$

Concept and Formula Used:

Scale Factor: It is the ratio of a length on a scale drawing or model to the corresponding length on the real object.

To find scle factor both the quantities must have same unit.

Calculation:

It is given that blueprint has a scale of $2inches=2feet$

Also, $1feet=12inches$

Therefore, $2feet=2\times 12inches=24inches$

Scale factor of blueprint is $=\frac{2}{24}=\frac{1}{12}$

Conclusion:

The scale factor of the blueprint is $\frac{1}{12}$ .
