To find the width of the dilated rectangle, you multiply the original width by the scale factor.
The original width of the rectangle is 16 inches, and the scale factor is 4.
So the calculation is:
\[ \text{Dilated width} = \text{Original width} \times \text{Scale factor} \] \[ \text{Dilated width} = 16 , \text{inches} \times 4 = 64 , \text{inches} \]
Therefore, the width of the dilated rectangle will be 64 inches.
