The enlargement will be 21 inches wide.

To find the width of the enlargement, first calculate the aspect ratio of the original photograph:
Aspect ratio = width / height
Aspect ratio = 5 / 3
Aspect ratio = 1.67

Then, use the aspect ratio to calculate the width of the enlargement:
Width of enlargement = aspect ratio x height of enlargement
Width of enlargement = 1.67 x 12.6
Width of enlargement = 21 inches

Therefore, the enlargement will be 21 inches wide.
