To find the area of the triangle, we can use the formula A = 1/2 * base * height.
The given triangle has a base of 3 feet and a corresponding height of 7 feet, as the right side is perpendicular to the bottom adjacent side and forms a right angle. Therefore, the area of the triangle is:
A = 1/2 * 3 ft * 7 ft = 10.5 ft²
None of the provided options match the correct answer. The correct area is 10.5 ft².
