Example Pt 2 The customer wants three pictures on the side of the page, they need to fit into an area which is 400 X 300 pixels. One of the pictures we have is currently 900 X 400. We need a way to accurately reduce this photo.

Maximum Area We have a photo that is 700 X 500 and we have an area on a web page that is 350 X 275. If we use the length as our first dimension the picture would resize as 350 X 250 If we use the width as our first dimension the picture would resize as 385 X 275 The first equation uses all but 25 pixels and the second number is too large, so the size using the maximum amount of area is 350 X 250.
