Sides increase by 2 times, area increase by 4 times

Step-by-step explanation:

The scale factor is a ratio that affect the sides of an object.

So, if we use a scale factor 2 to dilate a rectangle, its sides will increase 2 times.

As the area of the rectangle is the product between the length and the width, if the length increased by 2 times and the width as well, the area will increase by 2 * 2 = 4 times.
