The width of the border given the dimensions of the paper and the area of the photo is 13 inches.
What is the width of the border?
The first step is to determine the area of the piece of paper the photo was printed on.
Area of the piece of paper = length x width
13 x 15 = 195 inches square
The second step is to subtract the area of the picture from the area of the piece of paper: 195 - 143 = 52
Now, divide 52 by 4: 52/4 = 13 inches
