How do you calculate SCALE FACTOR?
scale factor = drawing/original
scale factor = reduction/original
scale factor = enlargement/original

What is the Scale Factor from triangle ABC to triangle DEF?
SF=3/6=1/2or0.5

The value of the unknown side length x is ...
Scale factor is 1/4 of the size of the original since 5/20 is 0.25 or 1/4. Therefore 24x0.25 or 1/4 of 24 is 6. x=6

On a scale drawing of a garden 2cm = 5m. If the length of the drawing is 10 cm, how long would the length of the garden be?
Scale factor is 5 since 2x5=10 therefore 5m x5 =25m. The garden length is 25m.

WHAT IS X?
7.5/5=x/8
x=7.5xx8-:5=12cm

The value of the unknown side length, ? is ...
15/12=25/x
x=12xx25-:15=20

The desk has a length of 75cm.
What is the scale diagram length if the scale factor is
1/3
The drawing of the desk is 1/3 of the size
so 25cm or
1/3=x/75
x=1xx75-:3=25cm

What is the value of x?
28/7=x/5
x=5xx28-:7=20

The value of the unknown side length ? is ...
Since 12 is top and bottom on the original
- 10 and 6 must match also.
6/10=x/12
x=6xx12-:10=7.2

The Lacrosse Field measures 99 m by 54 m. Using a scale factor of 0.002. What are the new measurements on the drawing?
L= 99mxx0.002=0.198m or 19.8cm
W=54mxx0.002=0.108m=10.8cm

A flagpole and a model flag pole have a scale of 1 cm = .4 m. If the pole in a picture measures 12 cm, how tall is the pole in m?
1/0.4=12/x
x=0.4xx12-:1=4.8m

An American football field is 360 m long.
What is the scale factor is the diagram shows the football field as 45 cm.
Change 360 m into cm by x 100= 36 000cm
