What scale factor was applied to the first rectangle to get the resulting image? enter your answer as a decimal in the box

The scale factor for the resultant rectangle is units.

Step-by-step explanation:

Given two rectangles with sides 3 units and 7.5 units.

We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.

Scale factor is defined as the ratio  of corresponding side of given figure to the corresponding side of resulting figure.

That is

Here,

Hence, the scale factor for the resultant rectangle is units.
