Scale factors are based on linear measures. The ratio of areas is the square of the rations of lengths. The ratio of the areas is 900/9 = 100, so the ratio of lengths is the square root of100 = 10.

How do you find the scale factor from 9 square cm to 900 square cm?
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
What is the scale factor for 5cm if the model is 58.7cm and actual is 140.9m?
the scale factor for a model is 5 cm + _________ m
How do you find the scale factor?
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
What is the scale factor of a photo measuring 2cm in length that corresponds to 100 meters in actual length?
It is 2 cm : 100 m or 2 cm : to 10000 cm which is equivalent to 1 to 5000
What is the area of a square with sides that are 6.3 cm in length?
The area of square is : 39.69
How do you find the scale factor from 9 square cm to 900 square cm?
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
What isa scale factor?
A scale factor in a number that changes the size of a shape by that scale examples: 1: if you have a square that is 1cm by 1cm and you increaseit by a scale factor of 3 the square would then be 3cm by 3cm 2: if you had a 2cm by 2 cm square and increase by a scale factor of 0.5 you'd get a 1cm by 1 cm square
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
If someone enlarged a drawing by a scale factor of 3 and got 396 cm squared what was the original drawing?
The scale factor is usually stated as a linear enlargement factor. Therefore, the area enlargement factor is the square of the scale factor, in this instance, 9. The area of the original drawing was thus 396/9 = 44 cm2.
What is the scale factor for 5cm if the model is 58.7cm and actual is 140.9m?
the scale factor for a model is 5 cm + _________ m
How many square feet are 900 square centimeters?
900 cm = approximately one (0.968751938) square foot.
What is the area of a rectangle that is 45 cm by 20 cm?
Area = 45*20 = 900 square cm
What is the scale factor for 4 cm equals 1 m?
1/400
A circle has an area of 900 pi sq cm what is the diameter?
pi * r2 = 900 pi [cm2] so r2 = 900 So the radius is the square root of 900 = 30 cm
What is the scale factor for 12 cm equals 18 m?
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
