A trapezoid is a quadrilateral with two parallel sides of different lengths. This means that any of the two sides can be called a base, and that the trapezoid is unique because it has two bases. the formula for finding the area of a trapezoid is [(b1 + b2) x h] / 2 Substituting the values: ((19 + 29.2) * (12.6)) / 2 303.66 in ^ 2 Answer: the area of the trapezoid is: 303.66 in ^ 2
