First, we need to find the perimeter of the original banner:
Perimeter = 2(length) + 2(width)
Perimeter = 2(7) + 2(5)
Perimeter = 14 + 10
Perimeter = 24 feet
Now we know that the new banner has the same perimeter, but a length of 6 feet:
24 = 2(6) + 2(width)
24 = 12 + 2(width)
12 = 2(width)
6 = width
Therefore, the new banner is 6 feet long and 6 feet wide.
Dax has a banner that is 7 feet long and 5 feet wide.
He wants a new banner that has the same
perimeter but is 6 feet long. How wide is the new banner?
