Delisa is designing a website that will be viewable on both computers and mobile devices, so the website as it is seen on a mobile device is proportional to the website as it is seen on a computer. The diagonal of Delisa's computer monitor is 21 inches, and the diagonal of Delisa's tablet is 9.6 inches.
If an image is 18 centimeters wide on the website when it's displayed on Delisa's computer, how wide should the image be on the tablet? Round to the nearest tenth of a millimeter, if necessary.
To find the width of the image on the tablet, we need to compare the ratio of the diagonals of the computer monitor and the tablet with the width of the image on the computer.
Let's first calculate the ratio of the diagonals:
Ratio = (tablet diagonal) / (computer diagonal) = 9.6 / 21 ≈ 0.4571
Now, we can use this ratio to find the width of the image on the tablet:
Width on tablet = (Ratio) * (Width on computer) = 0.4571 * 18 = 8.2278 centimeters
Therefore, the image should be approximately 8.2 centimeters wide on Delisa's tablet.
