What is the scale factor for a rectangle with a length of 6 units and a width of 4 units.

To find the scale factor, we need to compare the corresponding sides of two similar figures.

Let's compare the length of the rectangle to the length of the original figure. The length of the original figure is 6 units, and the length of the rectangle is also 6 units. So the length scale factor is 6/6 = 1.

Now, let's compare the width of the rectangle to the width of the original figure. The width of the original figure is 4 units, and the width of the rectangle is also 4 units. So the width scale factor is 4/4 = 1.

Since both the length and width scale factors are 1, the scale factor for the rectangle is 1.
