Answer: 30 sq ft
Step-by-step explanation: The area of a triangle can be calculated using the formula A = 1/2 * b * h, where A is the area, b is the base, and h is the height. In this case, the base of the triangle is 7 1/2 feet and the height is 8 feet, so the area is calculated as follows: A = 1/2 * 7.5 * 8 = 30 square feet. Therefore, the area of the triangle is 30 square feet.
