Answer: Possible width of the banner would be 8 feet.
Step-by-step explanation:
Since we have given that
Length of the banner = 15 feet
Length of ribbon available = 46 feet
Since the banner is in the form of rectangle using dark red with white ribbon border.
So, perimeter of banner would be 46 feet.
As we know the formula for "Perimeter of rectangle":
Perimeter = 2( length + Breadth)
Hence, Possible width of the banner would be 8 feet.
