Question

Andre drew a plan of a courtyard at a scale of 1 to 60 on his drawing one side of the courtyard is 2.75 inches. What is the actual measurement of that side of the courtyard

Answer 1

Answer:

$Real\hspace{3}length=165in$

Step-by-step explanation:

In order to calculate the real length, use scale length multiply the scale factor of it, then divide the scale factor of real length:

$Real\hspace{3}length=(Scale\hspace{3}length)*(Scale\hspace{3}ratio)^{-1}$

Where:

$Scale\hspace{3}length=2.75in\\Scale\hspace{3}ratio=\frac{1}{60}$

Therefore:

$Real\hspace{3}length=2.75*\frac{60}{1} =165in$
