A scale drawing of an object is of same shape as the object but at a different size. The ratio of two corresponding sides in similar figures is called the scale factor.
\[
\text { Scale factor }=\frac{\text { length in image }}{\text { corresponding length in object }}
\]
In the photograph shown below the scale is \( 1: 200 \).
The scale can also be written as the ratio of two lengths.
What is the actual width of the door if the width of the door in photograph is \( 0.5 \mathrm{~cm} \) ?
a. \( 1 \mathrm{~m} \)
b. \( 100 \mathrm{~m} \)
c. \( 0.05 \mathrm{~cm} \)
d. \( 50 \mathrm{~cm} \)
