A building that is 76 ft long would be shown as what length on a blueprint if the scale is $\frac{1}{2}$ in $=1 \mathrm{ft}$ ?
The length of the building drawn on the blueprint is $\square$ in.
Solution
Solution Steps
To find the length of the building on the blueprint, we need to use the given scale. The scale tells us that 1 foot in real life is represented by 0.5 inches on the blueprint. Therefore, we can multiply the actual length of the building by the scale factor to get the length on the blueprint.
Step 1: Determine the Scale
The scale provided is \( \frac{1}{2} \) in \( = 1 \) ft. This means that for every 1 foot of actual length, it is represented as \( \frac{1}{2} \) inch on the blueprint.
Step 2: Calculate the Length on the Blueprint
To find the length of the building on the blueprint, we multiply the actual length of the building by the scale factor:
\[
\text{Blueprint Length (in)} = \text{Actual Length (ft)} \times \text{Scale Factor}
\]
Substituting the values:
\[
\text{Blueprint Length (in)} = 76 \, \text{ft} \times \frac{1}{2} \, \text{in/ft} = 38 \, \text{in}
\]
Final Answer
The length of the building drawn on the blueprint is \\(\boxed{38 \, \text{in}}\\).
