Final answer:
The student has enough border for the square-shaped banner.
Step-by-step explanation:
Tre is making a square-shaped banner with each side measuring 24 inches. He wants to add a border along all sides. He has 75 inches of border. To find out if he has enough border, we need to calculate the total length of the sides of the square and compare it to the available border. The total length of the sides of the square is 24 inches for each side, so the perimeter of the square is 4 times the length of one side, which is 4 * 24 = 96 inches. Since Tre has 75 inches of border, which is less than the perimeter of the square, he does have enough border.
