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

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

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=(1)/(60)`

Therefore:

`Real\hspace{3}length=2.75*(60)/(1) =165in`
