Question

A building has a wall of windows that is 12 feet across. If a scale of 1:24 is used, how wide is the wall of windows on the drawing in inches?

Answer 1

Scale ratios are used to enlarge or compress an image.

The width of the wall on the drawing is $\frac{1 }{2}\ inches$

The scale is given as:

$Scale = 1 :24$

The scale ratio is represented as:

$Scale = Drawing : Actual$

So, we have:

$Drawing : Actual = 1 :24$

Substitute 12 for Actual

$Drawing : 12 = 1 :24$

Express as fraction

$\frac{Drawing }{ 12} = \frac{1 }{24}$

Multiply both sides by 12

$12 \times \frac{Drawing }{ 12} = \frac{1 }{24} \times 12$

$Drawing = \frac{1 }{2}$

Hence, the width of the wall on the drawing is $\frac{1 }{2}\ inches$
