The area of the trapezoid can be calculated using the formula A = 1/2 * h * (b1 + b2), where h is the height of the trapezoid, and b1 and b2 are the lengths of the two bases.
In this case, h = 6 cm, b1 = 12 cm, and b2 = 12 cm.
Therefore, A = 1/2 * 6 * (12 + 12) = 1/2 * 6 * 24 = 72 cm2
So, the area of the trapezoid is 72 cm2.
