What is the formula used to find the area of a trapezoid?

• A = (b1 + b2)h / 2, where b1 and b2 are the lengths of the two bases and h is the height.

• A = b * h, where b is the base and h is the height.

• A = (b1 - b2)h / 2, where b1 and b2 are the lengths of the two bases and h is the height.

• A = (b1 + b2) * h, where b1 and b2 are the lengths of the two bases and h is the height.
