Answer :
The actual measurement of that side of the courtyard = 165 inches
In this question, we have been given Andre drew a plan of a courtyard at a scale of 1 to 60. in his drawing, one side of the courtyard is 2.75 inches.
We need to find the actual measurement of that side of the courtyard.
In order to calculate the real length,
real length = scale length / scale ratio
here, scale length = 2.75 inches
scale ratio = (1/60)
so, the real length would be,
real length = 2.75/ (1/60)
real length = 2.75 * 60
real length = 165 inches
Therefore, the actual measurement of that side of the courtyard = 165 inches
