To find the area of a trapezoid, we use the formula A = 1/2 (b1 + b2)h, where b1 and b2 are the lengths of the two parallel bases and h is the height.
In this case, the lengths of the two parallel bases are 7 in and 12 in, and the height is 6 in.
A = 1/2 (7 + 12) 6
A = 1/2 (19) 6
A = 1/2 * 114
A = 57 in2
Therefore, the area of the figure is 57 in2.
The correct answer is 2. 57 in2.
