First, find the area of the triangle on the left side:
Area = (1/2) * base * height
Area = (1/2) * 14 * 8
Area = 56 in^2
Second, find the area of the triangle on the right side:
Area = (1/2) * base * height
Area = (1/2) * 10 * 8
Area = 40 in^2
Total area of the quadrilateral = Area of left triangle + Area of right triangle
Total area = 56 + 40 = 96 in^2
Therefore, the correct answer is not listed among the options provided. The closest answer is 102 in^2, but the correct answer based on the information provided is 96 in^2.
