If you dilate a rectangle with a width of 16 inches using a scale factor of 4, what will be the width of the dilated rectangle?

The width of the dilated rectangle will be 4 * 16 inches = 64 inches. Answer: \boxed{64}.

To find the width of the dilated rectangle, you need to multiply the width of the original rectangle by the scale factor. In this case, the scale factor is 4 and the width of the original rectangle is 16 inches.

To find the width of the dilated rectangle, you can use the formula:

Width of Dilated Rectangle = Scale Factor * Width of Original Rectangle

Plugging in the values:

Width of Dilated Rectangle = 4 * 16 inches

Width of Dilated Rectangle = 64 inches

Therefore, the width of the dilated rectangle will be 64 inches.
