The length scale factor = 5/3 So the area scale factor is (5/3)2 = 25/9
1 : 20
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
if 1 cm is 5km.... 3cm? 5+5+5 ..15km dirrtyy suckas!
8 cm x 10 cm
the scale factor for a model is 5 cm + _________ m
The length scale factor = 5/3 So the area scale factor is (5/3)2 = 25/9

Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.
It means that every 2 cm on the map would represent 5 miles in the real world.
5 cm = 0.05 m = 0.00005 km 2 km = 2000 m = 20000 cm
A scale factor tells how much the lengths in one diagram must be multiplied by to get the same lengths in a second.One diagram could be a map and the second the real world!To calculate the scale factor, measure the corresponding lengths in the same units and then divide the length of the second diagram by the length of the first diagram; this will give you the scale factor to convert the first diagram into the second diagram.For example, if you were to draw a map of you street, you may decide that 2 centimetres on the map will represent 1 metre in the real world.The ratio here is 2 cm : 1 m.However, 1 m = 100 cm which means that the ratio is 2 cm : 100 cmwhich is a scale factor of 100 cm ÷ 2 cm = 50.Another example: if you have two similar triangles and the corresponding sides measure as 5cm in the first triangle and 2 cm in the second, the scale factor is 2 cm ÷ 5 cm = 2/5 or 0.4
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
Look for corresponding parts of the two figures. Their ratio is the scale factor. For example, if you have two similar triangles, one has a side of length 3, and the corresponding side on the other triangle is 5, then the scale factor is 5/3 going from the small triangle to the big, or 3/5 going from the big triangle to the small.
To create a scale drawing that measures 20 meters by 15 meters using a scale of 1 cm to 5 meters, you would need to draw a rectangle that is 4 cm by 3 cm. Each centimeter on the drawing represents 5 meters in real life, so 4 cm would represent 20 meters and 3 cm would represent 15 meters.
You will see a distance of 5 cm on your map represent a 2 km distance across the landscape. Your 2 km is 2,000 meters, and there are 100 cm in a meter. That makes for 200,000 cm in 2 km. If you "reduce" or scale it down by a factor of 40,000, you'll get 200,000 / 40,000 = 5 cm.
if 1 cm is 5km.... 3cm? 5+5+5 ..15km dirrtyy suckas!
