To find the perimeter of the original banner, we use the formula for the perimeter of a rectangle:
Perimeter = 2(length) + 2(width)
Plugging in the values for the original banner, we get:
Perimeter = 2(7) + 2(5) = 14 + 10 = 24 feet
Now, we want the new banner to have the same perimeter but with a length of 6 feet. Let's call the width of the new banner W. Therefore, the new perimeter would be:
Perimeter = 2(6) + 2(W) = 12 + 2W
Since the new perimeter is the same as the original perimeter (24 feet), we can set up the equation:
12 + 2W = 24
2W = 12
W = 6
Therefore, the width of the new banner is 6 feet.
