The original photo has dimensions of 4 × 6. When enlarged, the width becomes 19.2. To maintain the same aspect ratio, we use the ratio of the new width to the old width to find the new length: $ \frac{19.2}{4} = 4.8 $. Multiplying the original length (6) by this factor gives the new length: $ 6 \times 4.8 = 28.8 $.
