Suppose an architect draws a segment on a scale drawing with the end points (0,0) and (3⁄4,9⁄10). The same segment on the actual
Kipish [7]

Segment drawn on scale having end points O (0,0) and A (\frac{3}{4},\frac{9}{10}) is a line segment.

O A= \sqrt{[\frac{3}{4} -0]^{2} +[\frac{9}{10} -0]^{2}\\\\

O A = = \sqrt{\frac{9}{16}+\frac{81}{100}

     = \sqrt\frac{549}{400}

    = \frac{\sqrt{549}}{20}

Now ,  the same segment actual structure having end points O'(0,0) and B (30,36) is also a line segment.

O'B= \sqrt{(30-0)^{2}+(36-0)^{2}

     = \sqrt{900+1296}

     = \sqrt {2196}

     = 2√549

\frac{\text{Actual length}}{\text{Length on scale}}=\frac{OB'}{OA}=\frac{2\sqrt549}{\frac{\sqrt549}{20}}=40 [Cancelling √549 from numerator and denominator]

So, Actual length = 40 × Length on scale
