Question

Jorge wants to determine the enlarged dimensions of a digital photo to be used as wallpaper on his computer screen. The original photo was 800 pixels wide by 600 pixels high. The new photo will be 1,260 pixels wide. What will the new height be?
460 pixels
945 pixels
1,680 pixels
1,860 pixels

Answer 1

Step 1: Find the scale factor from the original photo to the new photo
This is the formula you can use: \(Scale~Factor=\large \frac{End~length}{Start~length}\)

Step 2: You can use the scale factor to find the missing height
\(Missing~Height=(Original~Height)*(Scale~Factor)\)

Answer 2

Here are the values you can plug into the formulas I have suggested above^

End length = 1260
Start length = 800

Original Height = 600
