1:I read this to say that the lengths of the sides are reduced by a scale factor of 1/3. One of the sides has length 6.3 cm and one third of 6.3 is 13×6.3=2.1 cm. Thus the length of the new rectangle is 6.3 - 2.1 - 4.2 cm.
You can do this in one step. If you reduce the length by one third you are left with two thirds and 23×6.3=4.2.
2:The size of an enlargement/reduction is described by its scale factor. For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original.
3:Enlarge the triangle with scale factor 3, using O as the centre of enlargement. The diagram shows the 2 triangles; the explanation follows. First draw lines from point O through A, B and C, as shown in the diagram. Measure the length O A and multiply it by 3 to get the distance from O of the image point A', i.e.
4:is 8
1:I read this to state that the lengths of the sides are lessened by a scale factor of 1/3. One of the sides has length 6.3 cm and 33% of 6.3 is 13×6.3=2.1 cm. Accordingly the length of the new rectangle is 6.3 - 2.1 - 4.2 cm.
You can do this in one stage. In the event that you lessen the length by 33% you are left with 66% and 23×6.3=4.2.
2:The size of an augmentation/lessening is portrayed by its scale factor. For instance, a scale factor of 2 implies that the new shape is double the measure of the first. A scale factor of 3 implies that the new shape is three times the extent of the first.
3:Enlarge the triangle with scale factor 3, utilizing O as the focal point of extension. The graph demonstrates the 2 triangles; the clarification takes after. To start with draw lines from point O through A, B and C, as appeared in the chart. Measure the length O An and increase it by 3 to get the separation from O of the picture point An', i.e.
4:is 8
