A color photograph is 10 inches wide and 8 inches tall. If you want to make an enlargement of this photograph that is 16.8 inches​ tall, how wide will the enlargement​ be?

1 answer

First, we need to calculate the aspect ratio of the original photograph by dividing the width by the height:

Aspect ratio = width / height
Aspect ratio = 10 / 8
Aspect ratio = 1.25

Next, we can use the aspect ratio to calculate the width of the enlargement:

Width of enlargement = aspect ratio x height of enlargement
Width of enlargement = 1.25 x 16.8
Width of enlargement = 21 inches

Therefore, the enlargement will be 21 inches wide.
