Correct response: 6 feet
Explanation: The area of a triangle is calculated using the formula A = 1/2 * base * height. Given that the area is 7.5 square feet and the height is 2.5 feet, we can substitute these values into the formula to solve for the base:
7.5 = 1/2 * base * 2.5
15 = base * 2.5
base = 15 / 2.5
base = 6
Therefore, the length of the base of Ja'Miles' sign is 6 feet.
