Answer: 15 square feet
Explanation:
First, let's find the length and width of the actual banner. Looking at the drawing, we can see that the length of the banner is 5 inches and the width is 3 inches.
To convert the length and width from inches to feet, we use the scale of 1 inch representing 1 foot. So, the length of the actual banner is 5 feet and the width is 3 feet.
To find the area of the banner, we multiply the length by the width. So, the area of the actual banner is 5 feet * 3 feet = 15 square feet.
Therefore, the area of the actual banner is 15 square feet.
