For this problem we know that a scale drawing has a scale of 0.25 in=6 ft and we want to estimate the lenght of the draw with an actual lenght of 66ft. In order to solve the problem we can set up the following proportional rule:
[tex]\frac{0.25in}{6ft}=\frac{x}{66ft}[/tex]
With x the desired value. If we solve for x we got:
[tex]x=66ft\cdot\frac{0.25in}{6ft}=2.75in[/tex]
And then the lenght of the draw it would be 2.75 in for an actual lenght of 66 ft.
