How do you find the height of a trapezoid if the area and the lengths of the bases are given?
Use the formula: height = 2 * area / (length of base 1 + length of base 2)
height = area / (length of base 1 + length of base 2)
height = area * (length of base 1 + length of base 2)
height = area - (length of base 1 + length of base 2)

Explain how to solve for the height of a trapezoid using the area and the lengths of the bases.
height = area / (sum of the lengths of the bases)
height = (area) / (difference of the lengths of the bases)
height = (area) * (difference of the lengths of the bases)
height = 2 * (area) / (sum of the lengths of the bases)
