Answer 1

The scale factor is expressed as 2/7

Scale factor is described as a multiplier that shows how much larger or smaller a figure or object is compared to its original size when it is enlarged or reduced proportionally.

To determine the scale factor, we have the formula expressed as;

Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

Now, substitute the values, we have;

Scale factor = 20/70

Divide the values, we get;

Scale factor = 2/7
