The area of a trapezoid is given by the formula:
A = (b1 + b2) * h / 2
where b1 and b2 are the lengths of the two bases, and h is the height.
Plugging in the values given in the problem, we get:
A = (7 + 10) * 12 / 2
= 17 * 6
= 102
Therefore, the area of the trapezoid is 102 square meters. Answer: 102 m2.
