When the scale factor is 2, the area of a shape increases by a factor of the square of the scale factor. Therefore, if the original area is ( A ), the new area becomes ( 2^2 \times A = 4A ). This means the area quadruples when the dimensions of the shape are scaled by a factor of 2.
No, you cannot simply multiply the original area by the scale factor to get the new area. Instead, you need to square the scale factor and then multiply it by the original area. This is because area is a two-dimensional measurement, so any change in dimensions must be applied in both directions. For example, if the scale factor is 2, the new area will be 2² = 4 times the original area.
For areas: Square the Scale Factor.
Yes, the same relationship between the scale factor and area applies to similar triangles. If two triangles are similar, the ratio of their corresponding side lengths (the scale factor) is the same, and the ratio of their areas is the square of the scale factor. For example, if the scale factor is ( k ), then the area ratio will be ( k^2 ). This principle holds true for all similar geometric shapes, including rectangles and triangles.
With similar objects (where one is an exact scale version of the other) then if the linear measurements are in the ratio 2 : 3 then the areas are in the ratio 22 : 32 which equals 4 : 9. So if the sides of two triangles have a scale factor of 2/3 then the areas have a scale factor of 4/9.
The scale factor is 1 to 150

The area is directly proportional to the square of the scale factor. If the scale factor is 2, the area is 4-fold If the scale factor is 3, the area is 9-fold If the scale factor is 1000, the area is 1,000,000-fold
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
For areas: Square the Scale Factor.
The areas will be proportional to (scale)2
Yes, the same relationship between the scale factor and area applies to similar triangles. If two triangles are similar, the ratio of their corresponding side lengths (the scale factor) is the same, and the ratio of their areas is the square of the scale factor.

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.
With similar objects (where one is an exact scale version of the other) then if the linear measurements are in the ratio 2 : 3 then the areas are in the ratio 22 : 32 which equals 4 : 9. So if the sides of two triangles have a scale factor of 2/3 then the areas have a scale factor of 4/9.
A scale factor of 2.
The scale factor is 1 to 150
A scale factor of 2 means everything is shown in half the size of the original.
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
