Answer:
Greater
Explanation:
Area of the square sign = L²
L is the side length of the square
Given
L = 2 1/2 feet
Area of the sign = 2 1/2 * 2 1/2
Area of the sign = 5/2 * 5/2
Area of the sign = 25/4
Area of the sign = 8 1/4 square feet
This shows that the area of the sign will be greater than 2 1/2 square feet
